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.

Fix problems of not-starting image pullers
In e2e.go there are the following lines:
https://github.com/kubernetes/kubernetes/blob/master/test/e2e/e2e.go#L150
```
if err := framework.WaitForPodsSuccess(c, metav1.NamespaceSystem, framework.ImagePullerLabels, imagePrePullingTimeout); err != nil {
// There is no guarantee that the image pulling will succeed in 3 minutes
// and we don't even run the image puller on all platforms (including GKE).
// We wait for it so we get an indication of failures in the logs, and to
// maximize benefit of image pre-pulling.
framework.Logf("WARNING: Image pulling pods failed to enter success in %v: %v", imagePrePullingTimeout, err)
}
```
However, few lines above:
https://github.com/kubernetes/kubernetes/blob/master/test/e2e/e2e.go#L143
we were waiting for all image pullers to actually enter Success state. It's pretty clear that the latter wasn't expected.
This PR is fixing this problem.

Adding new tests to e2e/vsphere_volume_placement.go
Below is the tests description and test steps.
**Test Back-to-back pod creation/deletion with different volume sources on the same worker node**
1. Create volumes - vmdk2, vmdk1 is created in the test setup.
2. Create pod Spec - pod-SpecA with volume path of vmdk1 and NodeSelector set to label assigned to node1.
3. Create pod Spec - pod-SpecB with volume path of vmdk2 and NodeSelector set to label assigned to node1.
4. Create pod-A using pod-SpecA and wait for pod to become ready.
5. Create pod-B using pod-SpecB and wait for POD to become ready.
6. Verify volumes are attached to the node.
7. Create empty file on the volume to make sure volume is accessible. (Perform this step on pod-A and pod-B)
8. Verify file created in step 5 is present on the volume. (perform this step on pod-A and pod-B)
9. Delete pod-A and pod-B
10. Repeatedly (5 times) perform step 4 to 9 and verify associated volume's content is matching.
11. Wait for vmdk1 and vmdk2 to be detached from node.
12. Delete vmdk1 and vmdk2
**Test multiple volumes from different datastore within the same pod**
1. Create volumes - vmdk2 on non default shared datastore.
2. Create pod Spec with volume path of vmdk1 (vmdk1 is created in test setup on default datastore) and vmdk2.
3. Create pod using spec created in step-2 and wait for pod to become ready.

Loosen requirements of cluster logging e2e tests, make them more stable
There should be an e2e test for cloud logging in the main test suite, because this is the important part of functionality and it can be broken by different components.
However, existing cluster logging e2e tests were too strict for the current solution, which may loose some log entries, which results in flakes. There's no way to fix this problem in 1.6, so this PR makes basic cluster logging e2e tests less strict.

kubectl: Use v1.5-compatible ownership logic when listing dependents.
**What this PR does / why we need it**:
This restores compatibility between kubectl 1.6 and clusters running Kubernetes 1.5.x. It introduces transitional ownership logic in which the client considers ControllerRef when it exists, but does not require it to exist.
If we were to ignore ControllerRef altogether (pre-1.6 client behavior), we would introduce a new failure mode in v1.6 because controllers that used to get stuck due to selector overlap will now make progress. For example, that means when reaping ReplicaSets of an overlapping Deployment, we would risk deleting ReplicaSets belonging to a different Deployment that we aren't about to delete.
This transitional logic avoids such surprises in 1.6 clusters, and does no worse than kubectl 1.5 did in 1.5 clusters. To prevent this when kubectl 1.5 is used against 1.6 clusters, we can cherrypick this change.

e2e test: Log container output on TestContainerOutput error
When a pod started with TestContainerOutput or TestContainerOutputRegexp
fails from unknown reason, we should log all output of all its containers
so we can analyze what went wrong.
This would help us to see what wrong in https://github.com/kubernetes/kubernetes/issues/40811 - a container is running there for 3 minutes and dies and we want to see what it did for these 3 minutes.

Create DefaultPodDeletionTimeout for e2e tests
In our e2e and e2e_node tests, we had a number of different timeouts for deletion.
Recent changes to the way deletion works (#41644, #41456) have resulted in some timeouts in e2e tests. #42661 was the most recent fix for this.
Most of these tests are not meant to test pod deletion latency, but rather just to clean up pods after a test is finished.
For this reason, we should change all these tests to use a standard, fairly high timeout for deletion.

Don't wait for the final deletion of pod
The final deletion of the pod depends on kubelet and other components operating correctly. The purpose of this e2e test is verifying the clientset can handle deleteOptions correctly, so waiting for the deletionTimestamp and deletionGraceperiod get set is good enough.
In the long run, we should move this set of e2e tests to integration tests.

#41870 was reverted because it introduced an e2e test flake. This is the same code with the e2e for OIR disabled again.
We can attempt to enable the e2e test cases one-by-one in follow-up PRs, but it would be preferable to get the main fix merged in time for 1.6 since OIR is broken on master (see #41861).

Fix resource cleanup in ingress_utils.go within e2e/framework
**What this PR does / why we need it**:
The GLBC is failing to delete resources during the etcd rollback tests and the e2e cleanup is leaking them. After a short while, tests are failing to create new resources.
This PR addresses the e2e/framework's ability to delete GLBC-created resources and adds more logging.
**Which issue this PR fixes**:
Helps #38569 but does not completely close this flake
**Special notes for your reviewer**:
Resources were not being deleted because resource names were being truncated and then their ability to be deleted was determined by the entire cluster id existing in the name. Truncated names also have an extra '0' append to the end of their name (unknown origin). This PR tries to match on a common prefix.
Minor changes were made to improve log readability.
**Testing this PR**:
This was tested by running a master upgrade test and by adding a second forwarding-rule mid-run. This forwarding rule referenced the same url-map used by the first forwarding-rule created by the GLBC. Therefore, the GLBC will be able to delete the forwarding-rule but not anymore L7 resources. This second forwarding rule's name was nearly identical to the first forwarding rule so that the cleanup code will find it.
As you can see from the test run below, the cleanup code deleted all the resources that the GLBC could not.

Move node problem detector test into node e2e.
Move current NPD e2e test into node e2e.
In fact, current NPD e2e test is only a functionality test for NPD. It creates test NPD pod, sets test configuration, generates test logs and verifies test result.
It doesn't actually test the NPD really deployed in the cluster.
So it doesn't actually need to run in cluster e2e. Running it in node e2e will:
1) Make it easier to run the test.
2) Make it more light weight to introduce this as a pre/post submit test in NPD repo in the future.
Except this, I'm working on a cluster e2e to run some basic functionality test and benchmark test against the real NPD deployed in the cluster. Will send the PR later.

Guaranteed admission for Critical Pods
This is the first step in implementing node-level preemption for critical pods.
It defines the AdmissionFailureHandler interface, which allows callers, like the kubelet, to define how failed predicates are handled, and take steps to correct failures if necessary.
In the kubelet's implementation, it triggers preemption if the pod being admitted is critical, and if the only failed predicates are InsufficientResourceErrors, then it prempts (not yet implemented) other other pods to allow admission of the critical pod.

Together with the API endpoint, StorageClass annotation "storageclass.beta.kubernetes.io/is-default-class" is deprecated and "storageclass.kubernetes.io/is-default-class" should be used instead to mark a default storage class. The beta annotation is still working in this release, however it won't be supported in the next one.

Switch statefulset controller to shared informers
Originally part of #40097
I *think* the controller currently makes a deep copy of a StatefulSet before it mutates it, but I'm not 100% sure. For those who are most familiar with this code, could you please confirm?

Move pvutil.go from e2e package to framework package
**What this PR does / why we need it**:
This PR moves pvutil.go to the e2e/framework package.
I am working on a PV upgrade test, and would like to use some of the wrapper functions in pvutil.go. However, the upgrade test is in the upgrade package, and not the e2e package, and it cannot import the e2e package because it would create a circular dependency. So pvutil.go needs to be moved out of e2e in order to break the circular dependency. This is a refactoring name change, no logic has been modified.

e2e test for storage class diskformat verification for vsphere cloud provider
**What this PR does / why we need it**:
This PR adds a new e2e test for vsphere cloud provider.
Test is to verify diskformat specified in storage-class is being honored while volume creation.
Steps:
1. Create StorageClass with diskformat set to valid type (supported options are `eagerzeroedthick`, `zeroedthick` and `thin`)
2. Create PVC which uses the StorageClass created in step 1.
3. Wait for PV to be provisioned.
4. Wait for PVC's status to become Bound
5. Create POD using PVC on specific node.
6. Wait for Disk to be attached to the node.
7. Get node VM's devices and find PV's Volume Disk.
8. Get Backing Info of the Volume Disk and obtain Property of `VirtualDiskFlatVer2BackingInfo` - `EagerlyScrub` and `ThinProvisioned`
9. Based on the value of `EagerlyScrub` and `ThinProvisioned`, verify if diskformat is correct.
10. Delete POD and Wait for Volume Disk to be detached from the Node.
11. Delete PVC, PV and Storage Class

Isolate recycler behavior in PV E2E
**What this PR does / why we need it**:
Sets the default `reclaimPolicy` for PV E2E to `Retain` and isolates `Recycle` tests to their own context. The purpose of this is to future proof the PV test suite against the possible deprecation of the `Recycle` behavior. This is done by consolidating recycling test code into a single Context block that can be removed en masse without affecting the test suite.
Secondly, adds a liveliness check for the NFS server pod prior to each test to avoid maxing out timeouts if the NFS server becomes unavailable.

StatefulSet hardening
**What this PR does / why we need it**:
This PR contains the following changes to StatefulSet. Only one change effects the semantics of how the controller operates (This is described in #38418), and this change only brings the controller into conformance with its documented behavior.
1. pcb and pcb controller are removed and their functionality is encapsulated in StatefulPodControlInterface. This class modules the design contoller.PodControlInterface and provides an abstraction to clientset.Interface which is useful for testing purposes.
2. IdentityMappers has been removed to clarify what properties of a Pod are mutated by the controller. All mutations are performed in the UpdateStatefulPod method of the StatefulPodControlInterface.
3. The statefulSetIterator and petQueue classes are removed. These classes sorted Pods by CreationTimestamp. This is brittle and not resilient to clock skew. The current control loop, which implements the same logic, is in stateful_set_control.go. The Pods are now sorted and considered by their ordinal indices, as is outlined in the documentation.
4. StatefulSetController now checks to see if the Pods matching a StatefulSet's Selector also match the Name of the StatefulSet. This will make the controller resilient to overlapping, and will be enhanced by the addition of ControllerRefs.
5. The total lines of production code have been reduced, and the total number of unit tests has been increased. All new code has 100% unit coverage giving the module 83% coverage. Tests for StatefulSetController have been added, but it is not practical to achieve greater coverage in unit testing for this code (the e2e tests for StatefulSet cover these areas).
6. Issue #38418 is fixed in that StaefulSet will ensure that all Pods that are predecessors of another Pod are Running and Ready prior to launching a new Pod. This removes the potential for deadlock when a Pod needs to be rescheduled while its predecessor is hung in Pending or Initializing.
7. All reference to pet have been removed from the code and comments.
**Which issue this PR fixes**

**Special notes for your reviewer**:
**Release note**:
```release-note
Fixes issue #38418 which, under circumstance, could cause StatefulSet to deadlock.

e2e tests for vSphere cloud provider
**What this PR does / why we need it**:
This PR contains changes for existing e2e volume provisioning test cases for running on vsphere cloud provider.
**Following is the summary of changes made in existing e2e test cases**
**Added test/e2e/persistent_volumes-vsphere.go**
- This test verifies deleting a PVC before the pod does not cause pod deletion to fail on PD detach and deleting the PV before the pod does not cause pod deletion to fail on PD detach.
**test/e2e/volume_provisioning.go**
- This test creates a StorageClass and claim with dynamic provisioning and alpha dynamic provisioning annotations and verifies that required volumes are getting created. Test also verifies that created volume is readable and retaining data.
- Added vsphere as supported cloud provider. Also set pluginName to "kubernetes.io/vsphere-volume" for vsphere cloud provider.
**test/e2e/volumes.go**
- Added test spec for vsphere
- This test creates requested volume, mount it on the pod, write some random content at /opt/0/index.html and verifies file contents are perfect to make sure we don't see the content from previous test runs.
- This test also passes "1234" as fsGroup to mount volume and verifies fsGroup is set correctly.
**added test/e2e/vsphere_utils.go**
- Added function verifyVSphereDiskAttached - Verify the persistent disk attached to the node.
- Added function waitForVSphereDiskToDetach - Wait until vsphere vmdk is deteched from the given node or time out after 5 minutes
- Added getVSpherePersistentVolumeSpec - create vsphere volume spec with given VMDK volume path, Reclaim Policy and labels
- Added getVSpherePersistentVolumeClaimSpec - get vsphere persistent volume spec with given selector labels
- createVSphereVolume - function to create vmdk volume
**Following is the summary of new e2e tests added with this PR**
**test/e2e/vsphere_volume_placement.go**
- contains volume placement tests using node label selector
- Test Back-to-back pod creation/deletion with the same volume source on the same worker node
- Test Back-to-back pod creation/deletion with the same volume source attach/detach to different worker nodes
**test/e2e/pv_reclaimpolicy.go**
- contains tests for PV/PVC - Reclaiming Policy
- Test verifies persistent volume should be deleted when reclaimPolicy on the PV is set to delete and associated claim is deleted
- Test also verified that persistent volume should be retained when reclaimPolicy on the PV is set to retain and associated claim is deleted
**test/e2e/pvc_label_selector.go**
- This is function test for Selector-Label Volume Binding Feature.
- Verify volume with the matching label is bounded with the PVC.

Promote SubjectAccessReview to v1
We have multiple features that depend on this API:

- [webhook authorization](https://kubernetes.io/docs/admin/authorization/#webhook-mode)
- [kubelet delegated authorization](https://kubernetes.io/docs/admin/kubelet-authentication-authorization/#kubelet-authorization)
- add-on API server delegated authorization
The API has been in use since 1.3 in beta status (v1beta1) with negligible changes:
- Added a status field for reporting errors evaluating access
- A typo was discovered in the SubjectAccessReviewSpec Groups field name
This PR promotes the existing v1beta1 API to v1, with the only change being the typo fix to the groups field. (fixes https://github.com/kubernetes/kubernetes/issues/32709)
Because the API does not persist data (it is a query/response-style API), there are no data migration concerns.
This positions us to promote the features that depend on this API to stable in 1.7

Forgiveness library changes
**What this PR does / why we need it**:
Splited from #34825, contains library changes that are needed to implement forgiveness:
1. ~~make taints-tolerations matching respect timestamps, so that one toleration can just tolerate a taint for only a period of time.~~ As TaintManager is caching taints and observing taint changes, time-based checking is now outside the library (in TaintManager). see #40355.
2. make tolerations respect wildcard key.
3. add/refresh some related functions to wrap taints-tolerations operation.

Related issue: #1574

~~Since currently we have `pkg/api/helpers.go` and `pkg/api/v1/helpers.go`, there are some duplicated periods of code laying in these two files.~~
~~Ideally we should move taints-tolerations related functions into a separate package (pkg/util/taints), and make it a unified set of implementations. But I'd just suggest to do it in a follow-up PR after Forgiveness ones done, in case of feature Forgiveness getting blocked to long.~~

Remove many job e2e tests.
These tests have equivalent unit test coverage as far as I can tell, in [pkg/controller/job/jobcontroller_test.go](https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/job/jobcontroller_test.go). See #40839 for context.

test/node_e2e: wire-in cri-enabled local testing
This commit wires-in the pre-existing `--container-runtime` flag for
local node_e2e testing.
This is needed in order to further skip docker specific testing
and validation.
Local CRI node_e2e can now be performed via
`make test-e2e-node RUNTIME=remote REMOTE=false`
which will also take care of passing the appropriate argument to
the kubelet.

Add StatefulSets checks at Service level
Hi!
Please let me propose some very small e2e testsuite enhancement.
This PR removed a `TODO` about checking governing service at unit test level (which is hard) and adds this to e2e testsuite.
Thanks

Add websocket support for port forwarding
#32880
**Release note**:
```release-note
Port forwarding can forward over websockets or SPDY.
```
This commit wires-in the pre-existing `--container-runtime` flag for
local node_e2e testing.
This is needed in order to further skip docker specific testing
and validation.
Local CRI node_e2e can now be performed via
`make test-e2e-node RUNTIME=remote REMOTE=false`
which will also take care of passing the appropriate arguments to
the kubelet.
- split out port forwarding into its own package
Allow multiple port forwarding ports
- Make it easy to determine which port is tied to which channel
- odd channels are for data
- even channels are for errors
- allow comma separated ports to specify multiple ports
Add portfowardtester 1.2 to whitelist

Removed Flaky tag from PV e2e, added [Volume] to disruptive PV e2e
**What this PR does / why we need it**:
Removes `[Flaky]` from PV e2e testing. Flakes were due to interference from an external test disrupting a cluster node. The test has been [removed](9f36c032de) and the flakes have [cleared](https://k8s-testgrid.appspot.com/google-gce#gce-flaky).
Secondly, added `[Volume]` tag to PV disruptive tests.

refactor pv e2e code to improve readability
**What this PR does / why we need it**:
Moved the helper functions out of _persistent_volumes.go_ to a new file, _pvutil.go_, in order to improve readability and make it easier to add new tests.
Also, all pod delete code now calls the same helper function `deletePodWithWait`.

e2e test should fail if err==timeout
If err==timeout, it means the replicaset (the owner) is not deleted after 30s, which indicates a bug, so the e2e test should fail.

Retry resource quota lookup until count stabilizes
On contended servers the service account controller can slow down,
leading to the count changing during a run. Wait up to 5s for the count
to stabilize, assuming that updates come at a consistent rate, and are
not held indefinitely.

Fix federation component logging when e2e test case fails
When a federation e2e test case fails, federation component logs (esp. controller-manager) were very useful in debugging the failure cause. Due to recent updates in framework, the logs were not captured. This PR will fix those issues.

move pkg/fields to apimachinery
Purely mechanical move of `pkg/fields` to apimachinery.
Discussed with @lavalamp on slack. Moving this an `labels` to apimachinery.
@liggitt any concerns? I think the idea of field selection should become generic and this ends up shared between client and server, so this is a more logical location.

Add `rbac.authorization.k8s.io/v1beta1`. This scrubs `v1alpha1` to remove cruft, then add `v1beta1`. We'll update other bits of infrastructure to code to `v1beta1` as a separate step.
```release-note
The `attributeRestrictions` field has been removed from the PolicyRule type in the rbac.authorization.k8s.io/v1alpha1 API. The field was not used by the RBAC authorizer.

`pkg/api/errors` is a set of helpers around `meta/v1.Status` that help to create and interpret various apiserver errors. Things like `.NewNotFound` and `IsNotFound` pairings. This pull moves it into apimachinery for use by the clients and servers.
@smarterclayton @lavalamp First commit is the move plus minor fitting. Second commit is straight replace and generation.

Add optional per-request context to restclient
**What this PR does / why we need it**: It adds per-request contexts to restclient's API, and uses them to add timeouts to all proxy calls in the e2e tests. An entire e2e shouldn't hang for hours on a single API call.
**Which issue this PR fixes**: #38305
**Special notes for your reviewer**:
This adds a feature to the low-level rest client request feature that is entirely optional. It doesn't affect any requests that don't use it. The api of the generated clients does not change, and they currently don't take advantage of this.
I intend to patch this in to 1.5 as a mostly test only change since it's not going to affect any controller, generated client, or user of the generated client.

Remove sleep from DynamicProvisioner test.
The comment says that the sleep is there because of 10 minute PV controller
