Remove import of internal api package in generated external-versioned listers
Follow up of https://github.com/kubernetes/kubernetes/pull/44523
One line change in cmd/libs/go2idl/lister-gen/generators/lister.go, and simple changes in pkg/apis/autoscaling/v2alpha1/register.go, other changes are generated.
The internal api package will be eliminated from client-go, so these imports should be removed. Also, it's more correct to report the versioned resource in the error.
Add support for following redirects to the SpdyRoundTripper. This is
necessary for clients using it directly (e.g. the apiserver talking
directly to the kubelet) because the CRI streaming server issues a
redirect for streaming requests.
Also extract common logic for following redirects.
The Job Listers still use selectors, because this is the
behavior expected by callers. This clarifies the meaning of the
returned list. Some callers may need to switch to using
GetControllerOf() instead, but that is a separate, case-by-case issue.

Move v1/refs and v1/resource
This PR moves pkg/api/v1/ref.go and pkg/api/v1/resource_helper.go to their own sub packages, it's very similar to 44299 and 44302.
The PR is mostly mechanical, except that
* i moved some utility function from resource.go to pkg/api/v1/pod and pkg/api/v1/node, as they are more appropriate
* 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.

Move pkg/api/ref.go and pkg/api/resource_helpers.go to subpackages
First two commits are #44296#44299. (unfortunately, removing these commits results in conflicts)
This PR moves resource_helpers.go to a subpackage. It's mostly a mechanic move, except that:
* i kept the methods of ResourceName and ResourceList in pkg/api/method.go
I'll send one more PR to separate api.Scheme etc. to their own package.

Move pkg/api/ref.go to a subpackage
First commit is #44296. (unfortunately, removing that commit results in conflicts)
This PR moves the pkg/api/ref.go to its own subpackage. It's mostly a mechanic move.
I'll send a few more PRs to make the k8s.io/kubernetes/pkg/api package only contains the code we want in the k8s.io/api repo, then we can run a [script](a0015fd1be (diff-7a2fbb4371972350ee414c6b88aee1c8)) to cut the new repo.

Decouple remotecommand
Refactored unversioned/remotecommand to decouple it from undesirable dependencies:
- term package now is not required, and functionality required to resize terminal size can be plugged in directly in kubectl
- in order to remove dependency on kubelet package - constants from kubelet/server/remotecommand were moved to separate util package (pkg/util/remotecommand)
- remotecommand_test.go moved to pkg/client/tests module

Add the ability to lock on ConfigMaps to support HA for self hosted components
**What this PR does / why we need it**:
This PR add the ability to lock on ConfigMap objects. As we self-host more and more components, ConfigMaps provides a useful resource to lock on that applies to just the component that is being added.
This allows components such as scheduler+controller manager, etc. to have a simple mechanism to allow to active-passive HA without the cost of endpoint updates.
**Related Issues**
xref: https://github.com/kubernetes/client-go/issues/28
**Special notes for your reviewer**:
We may want to deprecate endpoints locking at some point.
**Release note**:

I noticed this when running kube-scheduler with --v4 and it is annoying.
Then manually reverted changed to the vendored bits.
The `System` and `Subsystem` parameters are subject to removal.

All metrics should use base units, which is seconds in the duration
case.
Counters should always end in `_total` and metrics should avoid
referring to potential label dimensions. Those should rather be
mentioned in the documentation string.

@erictune this is a prereq for moving CronJobs to beta. I initially planned to put all in one PR, but after I did that I figured out it'll be easier to review separately. ptal

RC/RS: Fully Respect ControllerRef
**What this PR does / why we need it**:
This is part of the completion of the [ControllerRef](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/controller-ref.md) proposal. It brings ReplicaSet and ReplicationController into full compliance with ControllerRef. See the individual commit messages for details.
**Which issue this PR fixes**:
Although RC/RS had partially implemented ControllerRef, they didn't use it to determine which controller to sync, or to update expectations. This could lead to instability or controllers getting stuck.

Add storage.k8s.io/v1 API
This is combined version of reverted #40088 (first 4 commits) and #41646. The difference is that all controllers and tests use old `storage.k8s.io/v1beta1` API so in theory all tests can pass on GKE.
Release note:
```release-note
StorageClassName attribute has been added to PersistentVolume and PersistentVolumeClaim objects and should be used instead of annotation `volume.beta.kubernetes.io/storage-class`. The beta annotation is still working in this release, however it will be removed in a future release.

client-go: don't import client auth provider packages
Both of these auth providers are useful for kubectl but not so much for everyone importing client-go. Let users optionally import them (example [0]) and reduce the overall number of imports that client-go requires.
Quick grep seems to imply it wont import it after.
