Update dummy certificate used in porter image
**What this PR does / why we need it**: the dummy certificate used for the porter image is incompatible with go1.8+ since it is missing NULL parameters for the RSA public key.
I haven't pushed the new porter image yet.
I verified that this appears to fix the issue. Based on https://github.com/kubernetes/kubernetes/issues/38228#issuecomment-280213590, for the old cert:
```console
$ openssl x509 -in localhost.crt -outform der | openssl asn1parse -inform der -i
...
105:d=4 hl=2 l= 9 prim: OBJECT :rsaEncryption
116:d=3 hl=2 l= 75 prim: BIT STRING
...
```
and the new cert:
```console
$ openssl x509 -in localhost.crt -outform der | openssl asn1parse -inform der -i
...
127:d=4 hl=2 l= 9 prim: OBJECT :rsaEncryption
138:d=4 hl=2 l= 0 prim: NULL

* i updated the staging/copy.sh to copy the new subpackages, so that helper functions are copied. We can get rid of this copy after client-go stops copying API types.

[Federation] Add type-agnostic e2e crud test
This PR proposes an e2e test that reuses the type-agnostic crudtester already used for integration testing to validate crud against a deployed cluster. It is intended to to eventually replace the existing e2e tests for simple types like secrets, but for now will run in addition to the existing testing to gain confidence in the coverage it provides.
The deletion corner cases - when orphanDependents is nil or true - do not involve operations in the member clusters and are already well-tested in integration testing and so are not reimplemented here.
Where it can be applied, this approach of abstracting a test from its execution environment - making the test 'retargetable' - can reduce the cost of test development since the bulk of the work can be iterated on as an integration test. It can also serve as a check on assumptions made in the integration test about how a deployed environment will behave.

Move v1 helpers
The first 3 commits are other PRs.
This PR move pkg/api/v1/helpers.go to a subpackage, which is almost symmetric to #44296, where pkg/api/helpers.go was moved.
This PR is mostly mechanic, except that
1. moved the 3 methods of Taint and Toleration to pkg/api/methods.go
2. moved constants and types defined in v1/helpers.go to pkg/api/v1/annotataion_key_constants.go and nonstandard_types.go
3. updated staging/copy.sh to copy pkg/api/helpers to client-go, it's otherwise removed from client-go because no other code in client-go depends on the package. Some test code in pkg/controller imports client-go/pkg/api/helpers. After moving api types to its own repo, we can remove these copies of utility function from client-go and ask users to use the ones in the main repo.
(This PR breaks a cyclic import problem i met when I tried to move global variables pkg/api/Scheme and Registry to a subpackage)

add kubelet tests to verify host clean up
**What this PR does / why we need it**:
Increasingly we're seeing more failures in persistent volume e2e tests where pv tests are run in parallel with disruptive tests. The quick solution is to tag the pv tests as Flaky. This pr addresses one cause of the flakiness and adds a disruptive kubelet test.
Once this pr is shown to not produce flakes the [Flaky] tag for the "HostCleanup" tests will be removed in a separate pr.
+ Adds volume tests to _kubelet.go_ motivated by issues [31272](https://github.com/kubernetes/kubernetes/issues/31272) and [37657](https://github.com/kubernetes/kubernetes/issues/37657)
+ Addresses reverted pr [41178](https://github.com/kubernetes/kubernetes/pull/41178) and negates the need for pr [41229](https://github.com/kubernetes/kubernetes/pull/41229)
**Which issue this PR fixes**

**Special notes for your reviewer**:
It's possible that one of the new tests, which relies on the existence of _/usr/sbin/rpc.nfsd_ in the nfs-server pod, will not work in the GCI container env. If this turns out to be true then I will add a `SkipIfProviderIs("gke")` to the `It` block.

Remove [Flaky] from presistent volume NFS tests.
**What this PR does / why we need it**:
PV e2e test flaked because of a lack of isolation of test objects (PVs, claims). The common symptoms being volume-mounting pods timing out or an unexpected number of unbound claims being detected.
PR #43645 Introduced the selector labels to test objects that restricted binds to within each "testspace". To accomplish this the test namespace was set as a label for all PVs and selector for all Claims. This allows each test to act as if it's isolated while still creating and binding PVs in parallel w/ other tests.
This has been tested in parallel on both 3-node gci and debian clusters as
`--ginkgo.focus="\[Volume\]" --ginkgo.skip="\[Disruptive\]|\[Feature.*\]|\[Serial\]"`
with out signs of flakiness.

Add a retry to cluster-autoscaler e2e
This should fix https://github.com/kubernetes/kubernetes/issues/44268.
The flake was caused by following sequence of events:
1. Cluster was at minimum size (3), some node was unneeded for a while.
2. Setup for some test (scale-down, failure) would increase node group size (to 5) and wait for new nodes to come up.
3. As soon as new node come up (cluster size 4) CA would scale-down the old unneeded node (setting node group size to 4).
4. Node group would not reach size 5 (as the target was now 4) and the test would timeout and fail.
This PR makes the setup monitor re-set the target node group size if the above scenario happens.

- refactor cluster helpers into framework so they can be reused by upgrade tests
- remove unused functions
- move backend pod management to the tests that require it rather than relying on the common cluster object
- use a slice instead of a map to manage cluster objects to make it simpler for tests that need it to find the primary cluster themselves
Commit ``fed: Refactor e2e cluster functions into framework for reuse`` was originally included in #43500, but is included here because it formed the basis for this cleanup.

[Federation] Add integration test for secrets
This PR adds an integration test for secrets that:
- performs create/read/update/delete on federation resources and validates that the changes are propagated to member clusters.
- uses an abstraction layer (fixture and adapter) to minimize the code required to support each federated type
- It should be possible to replace a test-specific adapter with a runtime adapter in the future (as per #41050)
- reuses fixture (federation api and clusters) across different resource types to minimize setup overhead
- on a fast machine, setup takes ~4s, and validating each type takes ~2s
- uses the [Subtest feature added in Go 1.7](https://blog.golang.org/subtests) to allow the test for a specific controller to be run in isolation
- ``make test-integration WHAT="federation -test.run=TestFederationCRUD/secret"``
Once this PR merges the test can be extended to target other federated types.

Fix original object mutation on patch retry
When applying a patch, the original state of the object and patch are captured so that retries can determine if an overlapping update was made to the object, and the patch API call should abort with a conflict.
However, the `strategicPatchObject -> applyPatchToObject -> StrategicMergeMapPatch -> mergeMap` call mutates both the original object map and the patch map, making them unsuitable for reusing for subsequent calls.
We saw this in a [downstream test](https://github.com/openshift/origin/blob/master/test/integration/patch_test.go) that exercises patch conflict retries, where the data being submitted in a patch was showing up in the original object data map.
Since mergeMap *also* mutates the patch map passed in (deletes patch directives as it encounters them), we *also* cannot reuse the patch map in `applyPatchToObject` once it has been used.
This PR:
* Builds `originalObjMap` separate from the initial patch application for later use in conflict detection
* Changes the `originalPatchMap` to a helper that returns a fresh map from original sources
* Adds an integration test that exercises retry of non-overlapping patches with patches containing `$patch` directives

**What this PR does / why we need it**:
There's a growing dependency on Volume e2e utilities related to creating / test against NFS volumes. For this reason, it's useful to relocate the relevant functions to the `framework` pkg. Doing so makes these utility functions available to e2e tests outside the `e2e` package.
This PR only moves code from the `e2e` package to `framework` and handle the relevant changes in calls. It does not change any logic.
```release-note
NONE
```
@jingxu97 I think there's value here in reducing duplicate code in the `common` package, given that these functions have been copied down to it. However, there's been some divergence. Can you PTAL and let me know if there's any reason we can't remove the duplicate `common` code?

Wait for clean old RSs statuses in the middle of Recreate rollouts
After https://github.com/kubernetes/kubernetes/pull/43508 got merged, we started returning ReplicaSets with no pods but with stale statuses back to the rollout functions. As a consequence, one of our e2e tests that checks if a Recreate Deployment runs pods from different versions, started flakying because the Deployment status may be incorrect. This change simply waits for the statuses to get cleaned up before proceeding with scaling up the new RS.

[Federation] Improve e2e test setup
This PR improves federation e2e test setup:
- reuses e2e framework setup (``NewDefaultFramework``) instead of duplicating it
- ensures ``FederationAfterEach`` is called if an error occurs in ``FederationBeforeEach`` (as per the [example](https://github.com/kubernetes/kubernetes/blob/master/test/e2e/framework/framework.go#L161) of the e2e framework)
- skips creation of a test namespace in the hosting cluster (not used for a federation e2e test)

```release-note
kube-apiserver: --service-account-lookup now defaults to true. This enables service account tokens to be revoked by deleting the Secret object containing the token.
```
- reuse default framework setup rather than duplicating
- skip namespace creation for each test in hosting cluster
- ensure FederationAfterEach is called if BeforeEach fails
Moved remaining util functions
moved cinder specific function back to volumes.go, will have to be extracted later when a cinder e2e package is created.
remove dupe code from common/volume.go
Moved [Volume] tags to KubeDescribe

node e2e: improve the validate OOM score test for infra containers
The test blindly checked all "pause" processes on the node, assuming
they were all infra containers. This change takes a snapshot of all
existing "pause" processes on the node, and exclude them in the
validation. The test still relies on the fact that it runs exclusively
on the node. If that assumption changes, we will need other methods to
locate the PIDs of the infra containers.
This fixes#37580

Move autoscaling e2e tests to a separate directory

test/e2e_node: prepull images with CRI
Part of https://github.com/kubernetes/kubernetes/issues/40739
- This PR builds on top of #40525 (and contains one commit from #40525)
- The second commit contains a tiny change in the `Makefile`.
- Third commit is a patch to be able to prepull images using the CRI (as opposed to run `docker` to pull images which doesn't make sense if you're using CRI most of the times)
Marked WIP till #40525 makes its way into master

tests: e2e-node: refactor node-problem-detector test to avoid selinux…
Fixes https://github.com/kubernetes/kubernetes/issues/43401
This test creates a file in /tmp on the host and creates a HostPath volume in the container to so that the host can inject messages into the logfile being read by the node problem detector in the container. However, selinux prohibits the container from reading files out of /tmp on the host.
This PR modifies the test to create the log file in an EmptyDir volume instead, which will be properly labeled for container access.

Adding test to perform volume operations storm
**What this PR does / why we need it**:
Adding new test to perform volume operations storm
Test Steps
1. Create storage class for thin Provisioning.
2. Create 30 PVCs using above storage class in annotation, requesting 2 GB files.
3. Wait until all disks are ready and all PVs and PVCs get bind. (**CreateVolume** storm)
4. Create pod to mount volumes using PVCs created in step 2. (**AttachDisk** storm)
5. Wait for pod status to be running.
6. Verify all volumes accessible and available in the pod.
7. Delete pod.
8. wait until volumes gets detached. (**DetachDisk** storm)
9. Delete all PVCs. This should delete all Disks. (**DeleteVolume** storm)
10. Delete storage class.

hack/lib/util.sh. Also consolidate ensure-temp-dir and use the
hack/lib/util.sh implementation rather than cluster/common.sh.

Apply [Feature:Volumes] to subset of tests in volumes.go
**What this PR does / why we need it**:
According to [this test doc](https://github.com/kubernetes/community/blob/master/contributors/devel/e2e-tests.md#kinds-of-tests), the `[Feature:xyz]` tag indicates that the tests have a non-default requirements and should not be run in the core suite. Previously all test in _e2e/volumes.go_ were tagged `[Feature:Volumes]` but I believe only six of the tests warrant this tag: iSCSI, GlusterFS, Ceph-RBD, Ceph-FS, vSPhere, and Cinder. The remaining tests (NFS, PD, ConfigMap) do not need the `Feature:` tag.
**Special notes for your reviewer**:
I moved the `[Volume]` tags from the `It`'s to the outer `KubeDescribe` to simplify the `It` text and remove redundancy.

De-Flake PersistentVolume E2E: Isolate resources with selectors
PersistentVolume tests continue to flake because tests Claims often bind to other, parallel tests' volumes. This is addressed by isolating test resource with selector labels specific to each test namespace. Doing so enables deterministic binding within each test space and allows tests to run in parallel.
1. Assign selector label to volumes and claims per test.
2. Remove `[Serial]` tag

replicaset adopt and release e2e tests
**What this PR does / why we need it**: adds e2e tests for replicaset pod adoption and release
**Which issue this PR fixes** fixes#39962
**Special notes for your reviewer**: for adoption pod is created, a replicaset with a selector matching the pod's label is created and then we check for the pod being in the list of pods of the replicaset. For release, a replicaset with two replicas is created, the label of one of them is patched and then we check that that pod is no longer in the list of pods of the replicaset.
For checking the list of pods the `framework.PodsCreated` is used, maybe the name is not very adecuate given that it is used to return the pods belonging to one replicaset, no matter how they were created. Also, the patching is done through `framework.KubectlOrDie`, not sure if this is better that calling the API directly.
