Previously, we used the docker config digest (also called "image ID"
by Docker) for the value of the `ImageID` field in the container status.
This was not particularly useful, since the config manifest is not
what's used to identify the image in a registry, which uses the manifest
digest instead. Docker 1.12+ always populates the RepoDigests field
with the manifest digests, and Docker 1.10 and 1.11 populate it when
images are pulled by digest.
This commit changes `ImageID` to point to the the manifest digest when
available, using the prefix `docker-pullable://` (instead of
`docker://`)

Rewrite summary e2e test to check metric sanity
Take two, forked from https://github.com/kubernetes/kubernetes/pull/28195
Adds a test library that extends the ginkgo matchers to check nested data structures. Then uses the new matcher library to thoroughly check the validity of every field in the summary metrics API. This approach is more flexible than the previous approach since it allows for different tests per-field, and is easier to add case-by-case exceptions. It also places the lower & upper bounds side-by-side, making the test much easier to read & reason about.
Most fields are expected to be within some bounds. This is not intended to be a performance test, so metric bounds are very loose. Rather, I'm looking to check that the values are sane to catch bugs like #27194Fixes#23411, https://github.com/kubernetes/kubernetes/issues/31989

separate RESTStorage by API group
This demonstrates how we could start separating the description of `RESTStorage` from `pkg/master`. Each API group owns constructing its own RESTStorage. Since `pkg/registry` is where we place all packages that create RESTStorage, it seems reason to split the package by `pkg/registry/<api group>/storage` to create RESTStorage and `pkg/registry/<api group>/<resource>` to support each individual resource.
The interface to construct this RESTStorage is dependent upon some `genericapiserver` types now, but we could (should?) move those items to a different location.
@kubernetes/sig-api-machinery
@lavalamp can you weigh in on how I've split these packages? I think we agree that we need better segregation, but we haven't spoken about how to spell it.

Node E2E: Add image white list
This is part of #29081. Fixes#29155.
As is discussed with @yujuhong in #29155, it is difficult to maintain the prepull image list if it is not enforced.
This PR added an image white list in the test framework, only images in the white list could be used in the test. If the image is not in the white list, the test will fail with reason:
```
Image "XXX" is not in the white list, consider adding it to CommonImageWhiteList in test/e2e/common/util.go or NodeImageWhiteList in test/e2e_node/image_list.go
```
Notice that if image pull policy is `PullAlways`, the image is not necessary to be in the white list or prepulled, because the test expects the image to be pulled during the test.
Currently, the image white list is only enabled in node e2e, because the image puller in e2e test is not integrated with the image white list yet.

add GenericAPIServer posthooks for initialization
Adds the concept of a `PostStartHook` to the `GenericAPIServer` to allow post-server start hooks. This gives a standard location to perform post-start bootstrapping tasks. The common case usage we have downstream are security related bootstrapping tasks that are performed on the "empty etcd" initialization cases. The RBAC authorizer is a good example of this in kube. It needs a location to create default policies to start a server which is capable of being accessed.
Kube is also likely to hit this for things like PSP and breaking the monolithic controller user into separate, scoped service accounts.
@kubernetes/sig-api-machinery for the `GenericAPIServer` bits

Version `v1.2.0` is a stable release of the previous release candidate `v1.2.0-beta.3`. The only difference is bumped Kubernetes deps to the lastest stable release `v1.4.0-beta.3` https://github.com/kubernetes/heapster/pull/1290.
It's low risk change. It may impact HPA and Monitoring e2e tests.

add local subject access review API
Adds a local subject access review endpoint to allow a project-admin (someone with full rights within a namespace) the power to inspect whether a person can perform an action in his namespace. This is a separate resource be factoring like this ensures that it is impossible for him to look outside his namespace and makes it possible to create authorization rules that can restrict this power to a project-admin in his own namespace. Other factorings require introspection of objects.

Add node e2e density test using 60 QPS for benchmark
This PR adds a new benchmark node e2e density test which sets Kubelet API QPS limit from default 5 to 60, through ConfigMap.

Add e2e tests that check for wrapped volume race
This PR adds two new e2e tests that reproduce the race condition fixed in #29641 (see e.g. #29297)
In order to observe the race, you need to revert the PR that fixes it, via e.g.
```
git revert -n df1e925143
```
or
```
curl -sL https://github.com/kubernetes/kubernetes/pull/29641.patch | patch -p1 -R
```
The tests are `[Slow]` because they need to run several passes that involve creating pods with many volumes. They also are `[Serial]` because the load on the cluster may affect reproducibility of the race. They take about ~450s each when they fail on standard GCE cluster created by `go run hack/e2e.go -v --up`. `git_repo` test takes about 66s to run when it succeeds (fix PR not reverted) and `configmap` test takes about 546s in this case because configmap mounting is slower and still requires 3 passes x 5 pods x 50 configmap volumes to fail constantly with fix PR reverted. Probably these times can be reduced but frankly I've already spent quite a bit of time on tuning the numbers to find a balance between reproducibility and speed.
Managed to reproduce the problem in more or less reliable way for `configMap` and `gitRepo` volumes. Tried to reproduce it for `secret` volumes too but without success so far because they use tmpfs-based `emptyDir` variety. For `downwardAPI` volumes I expect the same problems with race reproducibility as with `secret` volumes, although I think some e2e races were caused by the bug, e.g. #29633.
The tests operate by creating several pods (via an RC) with many volumes and waiting for them to become Running. It sets node affinity for pods so that they all get created on a single node (the first one in the node list). The race condition leads to volume mount failures with slow retries, thus causing the test to time out.
The test failures look like this:
configmap:

Generally, the races cause unexpected "no such directory" errors in kubelet logs with subsequent volume mount failures.
I've added race tests to e2e test `empty_dir_wrapper.go` ("EmptyDir wrapper volumes"). This test was added in #18445, the same PR that introduced the race bug. The original purpose of the test was making sure that no conflicts occur between different wrapped emptyDir volumes, so I've replaced "should becomes" with "should not conflict" in the first `It(...)`.

Move StorageClass to a storage group
We discussed the pros and cons in sig-api-machinery yesterday. Choosing a particular group name means that clients (including our internal code) require less work and re-swizzling to handle promotions between versions. Even if you choose a group you end up not liking, the amount of work remains the same as the incubator work case: you move the affected kind, resource, and storage.
This moves the `StorageClass` type to the `storage.k8s.io` group (named for consistency with authentication, authorization, rbac, and imagepolicy). There are two commits, one for manaul changes and one for generated code.

Pick a specific GCI version by default on GCE.
Prior to this change, a K8s branch (master as well as release) was
pinned to a GCI milestone. It would pick up the latest GCI release on
that milestone at the time of cluster creation. The rationale was the
K8s users would automatically get the bug fixes in newer versions of
GCI. However in practice, it makes the runtime environment
non-deterministic, and lack of continuous e2e tests mean we would run
into breakages sooner or later.
With this change, each K8s release will pick a specific version

Fix#31539
Adding 1.4 milestone as this fixes P0 flake issue (test completely broken by moving to gobindata). @pwittrock
cc @jayunit100
Prior to this change, a K8s branch (master as well as release) was
pinned to a GCI milestone. It would pick up the latest GCI release on
that milestone at the time of cluster creation. The rationale was the
K8s users would automatically get the bug fixes in newer versions of
GCI. However in practice, it makes the runtime environment
non-deterministic, and lack of continuous e2e tests mean we would run
into breakages sooner or later.
With this change, each K8s release will pick a specific version
of GCI by default (similar to how the Debian-based container-vm gets used).
Users can override the default version through KUBE_GCE_MASTER_IMAGE and
KUBE_GCE_NODE_IMAGE environment variables.
We expect the default GCI version will be updated relatively frequently stay
updated with newer GCI releases. We can also automate the process to
automatically bump the hard-coded GCI version in future.

#28921
@nikhiljindal @deepak-vij @quinton-hoole
This commit enables the dynamic kubelet configuration feature for the
node e2e Jenkins serial tests, which is where the test for dynamic kubelet
configuration currently runs.
This gives the node e2e test binary a --feature-gates flag that populates a
FeatureGates field on the test context. The value of this field is forwarded
to the kubelet's --feature-gates flag and is also used to populate the global
DefaultFeatureGate object so that statically-linked components see the same
feature gate settings as provided via the flag.
This means that you can set feature gates via the TEST_ARGS environment
variable when running node e2e tests. For example:
TEST_ARGS='--feature-gates=DynamicKubeletConfig=true'

Improve e2e framework namespace deletion
This PR addresses the following:
1. framework would delete same namespace multiple times in subsequent test if ns failed to delete in previous test. this caused incorrect error reporting on subsequent tests. updated framework to call delete on all namespaces, and then always clear out namespaces to delete.
1. deleteNs was not verifying all content was removed from the namespace, just pods. this made flakes hard to debug in tests that did not create pods and whose namespace didnt delete. updated framework to verify all content is removed from namespace.
1. improved debugging output when namespace did not delete with more detail on what remains.
This should stop the test from flaking while we figure out why there is
a mismatch between the reported pressure condition and the eviction
manager's decision to evict due to memory pressure.

Node E2E: Move host info around test result.
Discussed offline with @yujuhong and @dchen1107. Currently, the node e2e result is organized as:
```
================================================================
Success Finished Host tmp-node-e2e-b6c375c7-e2e-node-containervm-v20160321-image Test Suite
{ginkgo-output}
{framework-error}
================================================================
```
This makes it painful to find which image the test is failing on. The `{ginkgo-output}` is usually quite long, so we have to scroll mouse up and down to find the host name.
This PR changes the test result to:
```
================================================================
Start Host tmp-node-e2e-b6c375c7-e2e-node-containervm-v20160321-image Test Suite

```
This is not perfect, but much better than before. We can easily find the host name under the ginkgo test result, like this:
```

Fortunately, converting our cloud-init to json and calling it "ignition" works quite well 😄

[AppArmor] Promote AppArmor annotations to beta
Justification for promoting AppArmor to beta:
1. We will provide an upgrade path to GA
2. We don't anticipate any major changes to the design, and will continue to invest in this feature
3. We will thoroughly test it. If any serious issues are uncovered we can reevaluate, and we're committed to fixing them.
4. We plan to provide beta-level support for the feature anyway (responding quickly to issues).
Note that this does not include the yet-to-be-merged status annotation (https://github.com/kubernetes/kubernetes/pull/31382). I'd like to propose keeping that one alpha for now because I'm not sure the PodStatus is the right long-term home for it (I think a separate monitoring channel, e.g. cAdvisor, would be a better solution).

Delete the broken Celery+RabbitMQ example
The celery container used in the example is broken and does not come up
on most distros. The e2e test that was validating this example was not
detecting the fact the celery pod was crash looping.
I attempted to fix the celery container, but it proved to be tedious.
The proposed fix is to update the glibc version to >= 2.23. In this case
it requires updating the python docker image and the celery base image.
https://github.com/kubernetes/kubernetes/issues/31456
has more details.
I'm deleting the example instead of marking it as broken because a user
might overlook the broken warning and it should be trivial to revert
this PR if someone can fix the celery container.
This function does not actually attempt to connect to the docker daemon,
it just creates a client object that can be used to do so later. The old
name was confusing, as it implied that a failure to touch the docker daemon
could cause program termination (rather than just a failure to create the
client).

Node Conformance Test: Refactor node e2e framework
For #30122, #30174.
Based on #30348.
**Please only review the last 3 commits.**
This PR is part of our roadmap to package node conformance test.
The 1st commit is from #30348, it removed unnecessary dependencies in the node e2e test framework, because we've statically linked these dependencies.
The PR refactored the node e2e framework. Moving different utilities into different packages under `pkg/`.
We need to do this because:
1) Files like e2e_remote.go and e2e_build.go should only be used by runner, but they were compiled into the test suite because they were placed in the same package. The worst thing is that it will introduce some never used flags in the test suite binary.
2) Make the directory structure more clear. Only test should be placed in `test/e2e_node`, other utilities should be placed in different packages in `pkg/`.

- [x] add e2e tests
- [x] decide whether we want apiserver validation
- ~~[ ] add documentation~~: api docs exist. Existing PodSecurityContext docs is very light and links back to the api docs anyway: 6684555ed9/docs/user-guide/security-context.md

- [x] write e2e test for PodSecurityPolicy
- [x] make sure we are compatible in the sense of https://github.com/kubernetes/kubernetes/blob/master/docs/devel/api_changes.md
- [x] test e2e with rkt: it only works with kubenet, not with no-op network plugin. The later has no sysctl support.
- ~~[ ] add RunC implementation~~ (~~if that is already in kube,~~ it isn't)
- [x] update whitelist
- [x] switch PSC fields to annotations
- [x] switch PSP fields to annotations
- [x] decide about `--experimental-whitelist-sysctl` flag to be additive or absolute
- [x] decide whether to add a sysctl node whitelist annotation
### Release notes:
```release-note
The pod annotation `security.alpha.kubernetes.io/sysctls` now allows customization of namespaced and well isolated kernel parameters (sysctls), starting with `kernel.shm_rmid_forced`, `net.ipv4.ip_local_port_range`, `net.ipv4.tcp_max_syn_backlog` and `net.ipv4.tcp_syncookies` for Kubernetes 1.4.
The pod annotation `security.alpha.kubernetes.io/unsafeSysctls` allows customization of namespaced sysctls where isolation is unclear. Unsafe sysctls must be enabled at-your-own-risk on the kubelet with the `--experimental-allowed-unsafe-sysctls` flag. Future versions will improve on resource isolation and more sysctls will be considered safe.

[GarbageCollector] Allow per-resource default garbage collection behavior
What's the bug:
When deleting an RC with `deleteOptions.OrphanDependents==nil`, garbage collector is supposed to treat it as `deleteOptions.OrphanDependents==true", and orphan the pods created by it. But the apiserver is not doing that.
What's in the pr:
Allow each resource to specify the default garbage collection behavior in the registry. For example, RC registry's default GC behavior is Orphan, and Pod registry's default GC behavior is CascadingDeletion.

federation: Adding support for namespace admission controls in federation-apiserver
Now that we have namespaces in federation apiserver, we can support namespace admission controls.
There are 3 of these:
namespace/autoprovision, namespace/exists and namespace/lifecycle.
namespace/autoprovision, namespace/exists should be deprecated in kubernetes(https://github.com/kubernetes/kubernetes/issues/31195). Adding support for namespace/lifecycle to federation-apiserver.
As in kube-apiserver, enabling namespace/lifecycle by default.
```release-note
Action required: If you have a running federation control plane, you will have to ensure that for all federation resources, the corresponding namespace exists in federation control plane.
federation-apiserver now supports NamespaceLifecycle admission control, which is enabled by default. Set the --admission-control flag on the server to change that.
```

[e2e density test] Fix unnecessary Delete RC requests when not running latency test
As the following code block
https://github.com/kubernetes/kubernetes/blob/master/test/e2e/density.go#L666-L670
shows, after running each density test case, it will attempt to delete "additional replication controllers" even though there is **no additional replication controller**.
When we are not running latency test, API Server will return "404 error code". So, I propose to move the above code block inside thedetermine statementsif `itArg.runLatencyTest{ }` , looks like:
```
if itArg.runLatencyTest {
...
for i := 1; i <= nodeCount; i++ {
name := additionalPodsPrefix + "-" + strconv.Itoa(i)
c.ReplicationControllers(ns).Delete(name, nil)
}
}
```
In this way, removing RC will be executed only if we set `itArg.runLatencyTest` to be `true`. It can avoid post some necessary requests to API Server.

4. Support running benchmark in run_e2e.go. The benchmark configuration file is an extension of image configuration. Each item requires additional GCE machine type (e.g. n1-standard-1, default value will be used if empty) and test names (Ginkgo focus regex strings). A test item is regarded as benchmark if the tests field is non-empty.

OpenAPI / Swagger2 spec generation
This is alpha version of OpenAPI spec generation. Generated "/swagger.json" file (accessible on api server) is a valid OpenAPI spec with some warnings that will be fixed in next versions of spec generation. Currently it is possible to generate a client using this spec though I did not test the clients.
reference: #13414
**Release note**:
```release-note
Alpha support for OpenAPI (aka. Swagger 2.0) specification serves on /swagger.json

Node E2E: Make readiness check handling process exits with 0 exit code.
As is mentioned by @mtaufen:
"there is a problem with the way service `start` is currently implemented in test/e2e_node/e2e_service.go. If the Kubelet exits with status 0 before the health check completes, cmdErrorChan will be closed and, as a result, nil will be read from that channel, and you will return a nil error from `start`."
This PR changes the logic to:
1) If the err channel returns an error, return the error
2) If the err channel returns a nil, ignore it and continue checking readiness.
3) If the err channel is closed before readiness check succeeds, replace it with `blockCh` and continue checking readiness.

Move UTs that block on apiserver to integration tests.
In validating etcd.v3client we had uncovered that a change in the behavior of the client https://github.com/coreos/etcd/issues/6162 , caused a number of unit tests to fail. These test failures were due to the fact that the unit tests were trying to standup a apiserver even though there was no etcd backend stood up.
This PR simply shuffles those tests to integration tests, which is where they should be.

Implement dynamic provisioning (beta) of PersistentVolumes via StorageClass
Implemented according to PR #26908. There are several patches in this PR with one huge code regen inside.
* Please review the API changes (the first patch) carefully, sometimes I don't know what the code is doing...
* `PV.Spec.Class` and `PVC.Spec.Class` is not implemented, use annotation `volume.alpha.kubernetes.io/storage-class`
* See e2e test and integration test changes - Kubernetes won't provision a thing without explicit configuration of at least one `StorageClass` instance!
* Multiple provisioning volume plugins can coexist together, e.g. HostPath and AWS EBS. This is important for Gluster and RBD provisioners in #25026
* Contradicting the proposal, `claim.Selector` and `volume.alpha.kubernetes.io/storage-class` annotation are **not** mutually exclusive. They're both used for matching existing PVs. However, only `volume.alpha.kubernetes.io/storage-class` is used for provisioning, configuration of provisioning with `Selector` is left for (near) future.
* Documentation is missing. Can please someone write some while I am out?
For now, AWS volume plugin accepts classes with these parameters:
```
kind: StorageClass
metadata:
name: slow
provisionerType: kubernetes.io/aws-ebs
provisionerParameters:
type: io1
zone: us-east-1d
iopsPerGB: 10
```
* parameters are case-insensitive
* `type`: `io1`, `gp2`, `sc1`, `st1`. See AWS docs for details
* `iopsPerGB`: only for `io1` volumes. I/O operations per second per GiB. AWS volume plugin multiplies this with size of requested volume to compute IOPS of the volume and caps it at 20 000 IOPS (maximum supported by AWS, see AWS docs).
* of course, the plugin will use some defaults when a parameter is omitted in a `StorageClass` instance (`gp2` in the same zone as in 1.3).
GCE:
```
apiVersion: extensions/v1beta1
kind: StorageClass
metadata:
name: slow
provisionerType: kubernetes.io/gce-pd
provisionerParameters:
type: pd-standard
zone: us-central1-a
```
* `type`: `pd-standard` or `pd-ssd`
* `zone`: GCE zone
* of course, the plugin will use some defaults when a parameter is omitted in a `StorageClass` instance (SSD in the same zone as in 1.3 ?).

Allow setting permission mode bits on secrets, configmaps and downwardAPI files
cc @thockin @pmorie
Here is the first round to implement: https://github.com/kubernetes/kubernetes/pull/28733.
I made two commits: one with the actual change and the other with the auto-generated code. I think it's easier to review this way, but let me know if you prefer in some other way.
I haven't written any tests yet, I wanted to have a first glance and not write them till this (and the API) are more close to the "LGTM" :)
There are some things:
* I'm not sure where to do the "AND 0777". I'll try to look better in the code base, but suggestions are always welcome :)
* The write permission on group and others is not set when you do an `ls -l` on the running container. It does work with write permissions to the owner. Debugging seems to show that is something happening after this is correctly set on creation. Will look closer.
* The default permission (when the new fields are not specified) are the same that on kubernetes v1.3
* I do realize there are conflicts with master, but I think this is good enough to have a look. The conflicts is with the autog-enerated code, so the actual code is actually the same (and it takes like ~30 minutes to generate it here)
* I didn't generate the docs (`generated-docs` and `generated-swagger-docs` from `hack/update-all.sh`) because my machine runs out of mem. So that's why it isn't in this first PR, will try to investigate and see why it happens.
Other than that, this works fine here with some silly scripts I did to create a secret&configmap&downwardAPI, a pod and check the file permissions. Tested the "defaultMode" and "mode" for all. But of course, will write tests once this is looking fine :)
Thanks a lot again!

Fix killing child sudo process in e2e_node tests
Fixes#29211; re-doing #29380 which was reverted due to cross-platform build failure #29669.
The context is we are trying to kill a process started as `sudo kube-apiserver`, but `sudo` ignores signals from the same process group. Applying `Setpgid` means the `sudo kill` process won't be in the same process group, so will not fall foul of this nifty feature.
~~I also took the liberty of removing some code setting `Pdeathsig` because it claims to be doing something in the same area, but actually it doesn't do that at all. The setting is applied to the forked process, i.e. `sudo`, and it means the `sudo` will get killed if we (`e2e_node.test`) die. This (a) isn't what the comment says and (b) doesn't help because sending SIGKILL to the sudo process leaves sudo's child alive.~~
We do need to use the same 'hack' to access `Setpgid` as the `e2e_node.test` program gets built on Windows (although it doesn't run there).

Cut the client repo, staging it in the main repo
Tracking issue: #28559
ref: https://github.com/kubernetes/kubernetes/pull/25978#issuecomment-232710174
This PR implements the plan a few of us came up with last week for cutting client into its own repo:
1. creating "_staging" (name is tentative) directory in the main repo, using a script to copy the client and its dependencies to this directory
2. periodically publishing the contents of this staging client to k8s.io/client-go repo
3. converting k8s components in the main repo to use the staged client. They should import the staged client as if the client were vendored. (i.e., the import line should be `import "k8s.io/client-go/<pacakge name>`). This requirement is to ease step 4.
4. In the future, removing the staging area, and vendoring the real client-go repo.
The advantage of having the staging area is that we can continuously run integration/e2e tests with the latest client repo and the latest main repo, without waiting for the client repo to be vendored back into the main repo. This staging area will exist until our test matrix is vendoring both the client and the server.
In the above plan, the tricky part is step 3. This PR achieves it by creating a symlink under ./vendor, pointing to the staging area, so packages in the main repo can refer to the client repo as if it's vendored. To prevent the godep tool from messing up the staging area, we export the staged client to GOPATH in hack/godep-save.sh so godep will think the client packages are local and won't attempt to manage ./vendor/k8s.io/client-go.
This is a POC. We'll rearrange the directory layout of the client before merge.

This test creates three pods with QoS of besteffort, burstable, and
guaranteed, respectively, which each contain a container that tries to
consume almost all the available memory at a rate of about 12Mi/10sec.
The expectation is that eviction will be initiated when the hard
memory.available<250Mi threshold is triggered, and that eviction will proceed
in the order of besteffort, then burstable. Since guaranteed pods should
only be evicted if something charged to the host uses more resources
than were reserved for it, we currently end the test when besteffort and
burstable have both been evicted.
Note that this commit also sets --eviction-hard=memory.available<250Mi
to enable eviction during tests.

e2e flake: real fix of PodAntiAffinity test
The fix in PR https://github.com/kubernetes/kubernetes/pull/30135 was wrong in using a wrong test condition for an already broken test.
### Summary
The test tries to launch a pod with an anti-affinity annotation, waits 10
seconds and then checks that it is still pending.
But the anti-affinity annotation does not forbid to launch that pod on just
another node that does not have the zone label at all.
This commit changes this behavior by labeling two nodes with the zone label
and then forcing the pod to be launched on one of those two nodes.
**I assume here that a non-existing label is considered as a different label value.**

SchedulerExtender: add failedPredicateMap in Filter() returns
Fix#25797. modify extender.Filter for adding extenders information to “failedPredicateMap” in findNodesThatFit.
When all the filtered nodes that passed "predicateFuncs" don’t pass the extenders filter, the failedPredicateMap hasn’t the extenders information, should add it, I think. So when the length of the “filteredNodes.Items” is 0, we can know the integral information. (The length of the “filteredNodes.Items” is 0, may be because the extenders filter failed.)

Bug fix: Use p.Name instead of pod.Name
For example, if you used `pod.GenerateName`, `pod.Name` might be the empty

We need `go-bindata` to create `test/e2e/generated`, and downloading it with `go get` at build time is painful for a variety of reasons. We can just include it in the cross-build image and not worry about it, especially as it updates very infrequently.
This fixes `hack/update-generated-protobuf.sh` as well.

pv e2e refactor and pre-bind test
refactored persistentvolume e2e so that multiple It() tests can be run. Added one test case for pre-binding, but the overall structure of the test should allow additional test cases to be more easily added.

Resolve docker-daemon cgroup issue for both systemd and non-systemd node for node e2e tests
Fixed https://github.com/kubernetes/kubernetes/issues/29827
cc/ @coufon this should unblock your pr: #29764
I validated both containervm image and coreos image, and works as expected.
This is also required for adding gci image to node e2e test infrastructure.

Fix deployment e2e test: waitDeploymentStatus should error when entering an invalid state
Follow up #28162
1. We should check that max unavailable and max surge aren't violated at all times in e2e tests (didn't check this in deployment scaled rollout yet, but we should wait for it to become valid and then continue do the check until it finishes)
2. Fix some minor bugs in e2e tests

Fix 29992
Fix#29992.
I copied RC test code to the wrong place to the RS test in #29798. I took a look at the failure reports, they were all failed on the RS test, so #29798 itself is correct.
Marked as P2 since it fixes a test flake that will block everyone.

integration test: Modify PVs/PVCs during binding.
Previous volume binder code was not able to cope with PVs or PVCs getting modified during the binding process. Current one should be resilient to these changes, so let's test it.
It makes the test approximately twice as long as before, from ~2 seconds to ~4-5.

Add density (batch pods creation latency and resource) and resource performance tests to `test-e2e-node'
This PR contains two new tests (migrate from e2e test):
1. Density test: verify startup latency and resource usage when create a batch of pod with throughput control. Throughput control is done by sleep for an interval between firing concurrently create pod operations.
It tests both batch creation and sequential (back-to-back) creation and report the throughputs.
2. Verify resource usage of steady state kubelet.
The test creates a new resource controller for `test-node-e2e' (resource_controller.go) which monitors resource through a standalone Cadvisor pod (port 8090) with 1s housekeeping interval.

[Garbage Collector] add e2e tests again
#27151 is reverted because gke didn't start correctly after it's merged (https://github.com/kubernetes/kubernetes/pull/27151#issuecomment-233030686).
The possible problem is the `unbound variable`, which is fixed in the second commit of this PR. However, I cannot verify if the PR will fail the gke suite since I don't have the environment to run that suite.

Add support to quota pvc storage requests
Adds support to quota cumulative `PersistentVolumeClaim` storage requests in a namespace.
Per our chat today @markturansky @abhgupta - this is not done (lacks unit testing), but is functional.
This lets quota enforcement for `PersistentVolumeClaim` to occur at creation time. Supporting bind time enforcement would require substantial more work. It's possible this is sufficient for many, so I am opening it up for feedback.
In the future, I suspect we may want to treat local disk in a special manner, but that would have to be a different resource altogether (i.e. `requests.disk`) or something.
Example quota:
```
apiVersion: v1
kind: ResourceQuota
metadata:
name: quota
spec:
hard:
persistentvolumeclaims: "10"
requests.storage: "40Gi"
```

Node E2E: Make node e2e parallel
For https://github.com/kubernetes/kubernetes/issues/29081.
Fix https://github.com/kubernetes/kubernetes/issues/26215.
Based on https://github.com/kubernetes/kubernetes/pull/28807, https://github.com/kubernetes/kubernetes/pull/29020, will rebase after they are merged.
**Only the last commit is new.**
We are going to move more tests into the node e2e test. However, currently node e2e test only run sequentially, the test duration will increase quickly when we add more test.
This PR makes the node e2e test run in parallel so as to shorten test duration, so that we can add more test to improve the test coverage.
* If you run the test locally with `make test-e2e-node`, it will use `-p` ginkgo flag, which uses `(cores-1)` parallel test nodes by default.
* If you run the test remotely or in the Jenkin, the parallelism will be controlled by the environment variable `PARALLELISM`. The default value is `8`, which is reasonable for our test node (n1-standard-1).
Before this PR, it took **833.592s** to run all test on my desktop.
With this PR, it only takes **234.058s** to run.
The pull request node e2e run with this PR takes **232.327s**.
The pull request node e2e run for other PRs takes **673.810s**.

~~In scheduler predicates test, some tests won't clean pods they created when exit with failure, which may lead to pod leak. This PR is to fix it.~~

make the resource prefix in etcd configurable for cohabitation
This looks big, its not as bad as it seems.
When you have different resources cohabiting, the resource name used for the etcd directory needs to be configurable. HPA in two different groups worked fine before. Now we're looking at something like RC<->RS. They normally store into two different etcd directories. This code allows them to be configured to store into the same location.
To maintain consistency across all resources, I allowed the `StorageFactory` to indicate which `ResourcePrefix` should be used inside `RESTOptions` which already contains storage information.
@lavalamp affects cohabitation.
@smarterclayton @mfojtik prereq for our rc<->rs and d<->dc story.
