restrict discoverable versions to those that have resources
Prevents versions with no resources from appearing in discovery.
@soltysh ptal. I think you have some issues for this, mind wiring them up?
```
kubectl api-versions
apps/v1alpha1
authentication.k8s.io/v1beta1
authorization.k8s.io/v1beta1
autoscaling/v1
batch/v1
certificates.k8s.io/v1alpha1
extensions/v1beta1
policy/v1alpha1
rbac.authorization.k8s.io/v1alpha1
storage.k8s.io/v1beta1
v1
```
Fixes #29998.
- rename MuxHelper -> PathRecorderMux
- move non-rest handlers into routes packages within genericapiserver and
`pkg/routes` (those from master)
- move ui and logs handlers out of genericapiserver (they are
not generic)
- make version handler configurable (`config.EnableVersion`)

**What this PR does / why we need it**: The audit_test unit test fails as some iso8601 timestamps are of the form 2016-09-13T10:32:50.823081217Z and the current regex doesn't allow T's or Z's.

Do not report warning event when an unknown deleter is requested
When Kubernetes does not have a plugin to delete a PV it should wait for
either external deleter or storage admin to delete the volume instead of
throwing an error.
This is the same approach as in #32077

Etcd3 v3client + grpc client leak fix
This re-enables the client and plumbs through the destroyFunc to cleanup clients.
Fix for https://github.com/kubernetes/kubernetes/issues/31262
When we are mounting a lot of volumes, we frequently hit rate limits.
Reduce the frequency with which we poll the status; introduces a bit of
latency but probably matches common attach times pretty closely, and
avoids causing rate limit problems everywhere.
Also, we now poll for longer, as when we timeout, the volume is in an
indeterminate state: it may be about to complete. The volume controller
can tolerate a slow attach/detach, but it is harder to tolerate the
indeterminism.
Finally, we ignore a sequence of errors in DescribeVolumes (up to 5 in a
row currently). So we will eventually return an error, but a one
off-failure (e.g. due to rate limits) does not cause us to spuriously
fail.

Fix clientcmd for a non-host cluster client running in a pod.
This is based on @errordeveloper's PR #32438. It fixes a case where default config is invalid and original config, i.e. `mergedConfig` is empty. It also adds a test for the case where default config is invalid and original config is neither invalid nor empty.

Docker digest validation is too strict
Docker 1.10 does not guarantee that the pulled digest matches the digest
on disk when dealing with v1 schemas stored in a Docker registry. This
is the case for images like
centos/ruby-23-centos7@sha256:940584acbbfb0347272112d2eb95574625c0c60b4e2fdadb139de5859cf754bf
which as a result of #30366 cannot be pulled by Kube from a Docker 1.10
system.
This partially reverts commit 875fd16e1e.

Previusly github.com/robfig/cron library did not allow passing cron spec without
seconds. Previous commit updates the library, which has additional
method ParseStandard which follows the standard cron spec, iow. minute,
hour, day of month, month, day of week.
Docker 1.10 does not guarantee that the pulled digest matches the digest
on disk when dealing with v1 schemas stored in a Docker registry. This
is the case for images like
centos/ruby-23-centos7@sha256:940584acbbfb0347272112d2eb95574625c0c60b4e2fdadb139de5859cf754bf
which as a result of #30366 cannot be pulled by Kube from a Docker 1.10
system.
Instead, use RepoDigests field as the primary match, validating the
digest, and then fall back to ID (also validating the match). Adds more
restrictive matching.

Recombine the condition for the "shouldScale" function
The PR recombine the condition for the "shouldScale" function, abstract the common condition(hpa.Status.LastScaleTime == nil).
Two problems:
1. Get is always using Existing nodes slice, and you will for sure miss any
updated data
2. Each Update duplicates node entry in UpdatedNodes slice
For the 1st, try to find a node in UpdatedNodes slice (same as for the List).
2nd - append only if there is no node with same name as updated, if there is
just replace object.

add local subject access review API
Adds a local subject access review endpoint to allow a project-admin (someone with full rights within a namespace) the power to inspect whether a person can perform an action in his namespace. This is a separate resource be factoring like this ensures that it is impossible for him to look outside his namespace and makes it possible to create authorization rules that can restrict this power to a project-admin in his own namespace. Other factorings require introspection of objects.
