Update Google API dependencies

In order to experiment with alpha or beta GCP APIs (that are new), we need to make the client compatible with v1 client. And there were some cosmetic changes that make them incompatible with the version that we were using before (e.g. passing pointers vs non-pointers in gensupport functions).

Add work queues to PV controller

PV controller should not use Controller.Requeue, as as it is not available in
shared informers. We need to implement our own work queues instead, where we
can enqueue volumes/claims as we want.

kubectl: ignore deleted pods in the rolling updater

Fixes https://github.com/kubernetes/kubernetes/issues/37955

The Deployment controller already ignores deleted pods or more precisely the ReplicaSet controller ignores deleted pods ([pod classification](https://github.com/kubernetes/kubernetes/blob/a30b6e2d163ce5363daf1106350f46ea99982a64/pkg/controller/replicaset/replica_set.go#L600) ignores [deleted pods](https://github.com/kubernetes/kubernetes/blob/a30b6e2d163ce5363daf1106350f46ea99982a64/pkg/controller/controller_ref_manager.go#L63)) and the Deployment controller reuses what's in the ReplicaSet status.

Add Persistent Volume E2E in the context of a disrupted kubelet

This PR adds a test suite for persistent volumes affected by a disrupted kubelet.  Two cases are presented:

1.  A volume mounted via PVC remains accessible after a kubelet restart.
2.  When a pod is deleted while the kubelet is down, the mounted volume is unmounted successfully.

PV controller should not use Controller.Requeue, as as it is not available in
shared informers. We need to implement our own work queues instead where we
can enqueue volumes/claims as we want.

Recycle Pod Template Check

The kube-controller-manager has two command line arguments (--pv-recycler-pod-template-filepath-hostpath and --pv-recycler-pod-template-filepath-nfs) that specify a recycle pod template. The recycle pod template may not contain the volume that shall be recycled.

A check is added to make sure that the recycle pod template contains at least a volume.

Kubelet: add image ref to ImageService interfaces

This PR adds image ref (digest or ID, depending on runtime) to PullImage result, and pass image ref in CreateContainer instead of image name. It also

* Adds image ref to CRI's PullImageResponse
* Updates related image puller
* Updates related testing utilities

~~One remaining issue is: it breaks some e2e tests because they [checks image repoTags](https://github.com/kubernetes/kubernetes/blob/master/test/e2e/framework/util.go#L1941) while docker always returns digest in this PR. Should we update e2e test or continue to return repoTags in `containerStatuses.image`?~~

Fixes #38833.

cluster/gce: Rename coreos to container-linux.

Since coreos distro has been be renamed to container linux, we need to follow the naming convention here as well.

We also need to rename the libvirt-coreos as well, but to make review easier, that will happen in another PR.

Curating Owners: pkg/genericapiserver

cc @lavalamp @smarterclayton @nikhiljindal

In an effort to expand the existing pool of reviewers and establish a
two-tiered review process (first someone lgtms and then someone
experienced in the project approves), we are adding new reviewers to
existing owners files.


If You Care About the Process:
------------------------------

We did this by algorithmically figuring out who’s contributed code to
the project and in what directories.  Unfortunately, that doesn’t work
well: people that have made mechanical code changes (e.g change the
copyright header across all directories) end up as reviewers in lots of
places.

Instead of using pure commit data, we generated an excessively large
list of reviewers and pruned based on all time commit data, recent
commit data and review data (number of PRs commented on).

At this point we have a decent list of reviewers, but it needs one last
pass for fine tuning.

Also, see https://github.com/kubernetes/contrib/issues/1389.

TLDR:
-----

As an owner of a sig/directory and a leader of the project, here’s what
we need from you:

1. Use PR https://github.com/kubernetes/kubernetes/pull/35715 as an example.

2. The pull-request is made editable, please edit the `OWNERS` file to
remove the names of people that shouldn't be reviewing code in the
future in the **reviewers** section. You probably do NOT need to modify
the **approvers** section. Names asre sorted by relevance, using some
secret statistics.

3. Notify me if you want some OWNERS file to be removed.  Being an
approver or reviewer of a parent directory makes you a reviewer/approver
of the subdirectories too, so not all OWNERS files may be necessary.

4. Please use ALIAS if you want to use the same list of people over and
over again (don't hesitate to ask me for help, or use the pull-request
above as an example)

Ssh fix

**What this PR does / why we need it**:
Use the dial timeout provided by the SSH library to prevent the dangling connections.

fixes #33472

**Special notes for your reviewer**:
I did not set the TCP Timeout or Deadlines. That will take more work but wasn't sure if it is needed. More importantly, I wasn't sure what values we would want to use.
