Support exec/attach/portforward in `kubectl proxy`
Use the UpgradeAwareProxy shared code in kubectl proxy. Provide a separate transport for those requests that does not have HTTP/2 enabled. Refactor the code to be a bit cleaner in places and to better separate changes.
Fixes#32026
```release-note
`kubectl proxy` will now correctly handle the `exec`, `attach`, and `portforward` commands. You must pass `--disable-filter` to the command in order to allow these endpoints.

Improve GC discovery sync performance by only syncing when discovered
resource diffs are detected. Before, the GC worker pool was shut down
and monitors resynced unconditionally every sync period, leading to
significant processing delays causing test flakes where otherwise
reasonable GC timeouts were being exceeded.

Fix local storage test failures
**What this PR does / why we need it**:
Fixed a few issues:
- CI environment on GCE cannot resolve node names, need to use IPs. Use a different SSH wrapper that will get the IPs from the node object.
- Use hostdir instead of containerdir now that commands are executed directly on the host, instead of through a container.
- Get the PVC object again after it is bound so that it has the PV name.

Deprecate Deployment .spec.rollbackTo field
~Depends on #48746~ (merged)
xref: #46934, #49135
1. Deprecate Deployment field `.spec.rollbackTo` in `extensions/v1beta1` and `apps/v1beta1`, and remove the same field and `/rollback` endpoint from `apps/v1beta2` Deployment.
1. Add an annotation `deprecated.deployment.rollback.to` in `apps/v1beta2` for conversion to/from other versions.
Note: `apps/v1beta2` is new in 1.8 (and WIP), so it is okay to make breaking changes to it.
```release-note
Deprecate Deployment .spec.rollbackTo field
```
Currently, in federated end2end tests, the creation of services are
done with a randomize NodePort selection. It causing e2e test
flakes if the creation of a federated service failed if the port is
not available.
Now the util.CreateService(...) function is re trying to create the
service on different nodePort in an error case. The method retries until
success or 10 creation retry with other random NodePorts.
If never the service has not been created properly on one of the
federated cluster, a Service shards cleanup is executed before retrying
again the federated service creation.

Let controllers ignore initialization timeout when creating pods
Partially address https://github.com/kubernetes/kubernetes/issues/48893#issuecomment-318540129.
This only updates the controllers that create pods with `GenerateName`.
The controllers ignore the timeout error when creating the pods, depending on how the initialization progress:
* If the initialization is successful in less than 5 mins, the controller will observe the creation via the informer. All is good.
* If the initialization fails, server will delete the pod, but the controller won't receive any event. The controller will not create new pod until the Creation expectation expires in 5 min.
* If the initialization takes too long (> 5 mins), the Creation expectation expires and the controller will create extra pods.
I'll send follow-up PRs to fix the latter two cases, e.g., by refactoring the sharedInformer.

Add basic install and mount flexvolumes e2e tests
fixes https://github.com/kubernetes/kubernetes/issues/47010
These two tests install a skeleton "dummy" flex driver, attachable and non-attachable respectively, then test that a pod can successfully use the flex driver. They are labeled disruptive because kubelet and controller-manager get restarted as part of the flex install. IMO it's important to keep this install procedure as part of the test to isolate any bugs with the startup plugin probe code.
There is a bit of an ugly dependency on cluster/gce/config-test.sh because --flex-volume-plugin-dir must be set to a dir that's readable from controller-manager container and writable by the flex e2e test. The default path is not writable on GCE masters with read-only root so I picked a location that looks okay.
In the "dummy" drivers I trick kubelet into thinking there is a mount point by doing "mount -t tmpfs none ${MNTPATH} >/dev/null 2>&1", hope that is okay.
I have only tested on GCE and theoretically they may work on AWS but I don't think there is a need to test on multiple cloudproviders.

improve detectability of deleted pods
**What this PR does / why we need it**:
Adds comment to `waitForPodTerminatedInNamespace` to better explain how it's implemented.
~~It improves pod deletion detection in the e2e framework as follows:~~
~~1. the `waitForPodTerminatedInNamespace` func looks for pod.Status.Phase == _PodFailed_ or _PodSucceeded_ since both values imply that all containers have terminated.~~
~~2. the `waitForPodTerminatedInNamespace` func also ignores the pod's Reason if the passed-in `reason` parm is "". Reason is not really relevant to the pod being deleted or not, but if the caller passes a non-blank `reason` then it will be lower-cased, de-blanked and compared to the pod's Reason (also lower-cased and de-blanked). The idea is to make Reason checking more flexible and to prevent a pod from being considered running when all of its containers have terminated just because of a Reason mis-match.~~

Reduce GC e2e test flakiness
Increase GC wait timeout in a flaky e2e test. The test expects a GC
operation to be performed within 30s, while in practice the operation
often takes longer due to a delay between the enqueueing of the owner's
delete operation and the GC's actual processing of that event. Doubling
the time seems to stabilize the test. The test's assumptions can be
revisited, and the processing delay under load can be investigated in
the future.

Add node e2e tests for GKE environment
Ref: https://github.com/kubernetes/kubernetes/issues/46891
This PR adds node e2e tests for validating images used on GKE.
- We pass the `SYSTEM_SPEC_NAME` to the node e2e test process via the flag `--system-spec-name` so that we can skip the environment specific tests using `RunIfSystemSpecNameIs()`.
- Also added `SkipIfContainerRuntimeIs()` as the opposite of `RunIfContainerRuntimeIs()`.
**Release note**:

Enhance the garbage collector to periodically refresh the resources it
monitors (via discovery) to enable custom resource definition GC.
This implementation caches Unstructured structs for any kinds not
covered by a shared informer. The existing meta-only codec only supports
compiled types; an improved codec which supports arbitrary types could
be introduced to optimize caching to store only metadata for all
non-informer types.

Remove default binding of system:node role to system:nodes group
part of https://github.com/kubernetes/features/issues/279
deprecation of this automatic binding announced in 1.7 in https://github.com/kubernetes/kubernetes/pull/46076
```release-note
RBAC: the `system:node` role is no longer automatically granted to the `system:nodes` group in new clusters. It is recommended that nodes be authorized using the `Node` authorization mode instead. Installations that wish to continue giving all members of the `system:nodes` group the `system:node` role (which grants broad read access, including all secrets and configmaps) must create an installation-specific `ClusterRoleBinding`.

Remove hostname label condition in SchedulerPredicates
**What this PR does / why we need it**:
```
validates that NodeSelector is respected if matching [Conformance]
validates that required NodeAffinity setting is respected if matching
```
The two tests above make the assumption that the node names are equal to the `kubernetes.io/hostname` labels. Unfortunately, this is not necessarily true all the time. For instance, when using the AWS Cloud Provider + Container Linux:
- The node name is set using the AWS SDK's `ec2.Instance.PrivateDnsName` and has the form `ip-10-0-35-57.ca-central-1.compute.internal` [[1](https://github.com/kubernetes/kubernetes/blob/v1.7.1/pkg/cloudprovider/providers/aws/aws.go#L3343-L3346)] [[2](https://raw.githubusercontent.com/aws/aws-sdk-go/master/service/ec2/api.go)]
- The node's hostname, however, is a simple call to `os.Hostname()`, itself reading `/proc/sys/kernel/hostname`, which contains what the AWS DHCP assigned to the instance, typically the hostname short-form: `ip-10-0-16-137`. [[1](https://github.com/kubernetes/kubernetes/blob/v1.7.1/pkg/util/node/node.go#L43-L54)]
Consequently, we are trying to assign a pod to a node having the following label: `kubernetes.io/hostname=ip-10-0-35-57.ca-central-1.compute.internal` (in addition to the randomly generated label), whereas the actual label on the node is `kubernetes.io/hostname=ip-10-0-35-57`.
Furthermore, this inaccurate `kubernetes.io/hostname=<nodename>` condition is actually useless given we already match over a random label, that was assigned to that node. Later, the test ensures that the scheduled pod was scheduled to the right node by comparing the pod's node name and the node name we expected the pod to be on:
```
framework.ExpectNoError(framework.WaitForPodNotPending(cs, ns, labelPodName))
labelPod, err := cs.Core().Pods(ns).Get(labelPodName, metav1.GetOptions{})
framework.ExpectNoError(err)
Expect(labelPod.Spec.NodeName).To(Equal(nodeName))
```
The `k8s.io/apimachinery/pkg/types/nodename` data structure actually [warns](55bee3ad21/staging/src/k8s.io/apimachinery/pkg/types/nodename.go (L40-L43)) about the fact that the node name might be different than the hostname on AWS.

StatefulSet: Remove `pod.alpha.kubernetes.io/initialized` annotation.
The `pod.alpha.kubernetes.io/initialized` annotation was originally a tool for validating StatefulSet's ordered Pod creation guarantees during the feature's alpha phase.
If set to "false" on a given Pod, it would interrupt StatefulSet's normal behavior. In v1.5.0, the annotation was deprecated and the default became "true" as part of StatefulSet's graduation to beta.
The annotation is now ignored, meaning it cannot be used to interrupt StatefulSet Pod management.
```release-note
StatefulSet: The deprecated `pod.alpha.kubernetes.io/initialized` annotation for interrupting StatefulSet Pod management is now ignored. If you were setting it to `true` or leaving it unset, no action is required. However, if you were setting it to `false`, be aware that previously-dormant StatefulSets may become active after upgrading.
```
