Regenerate all BUILD files in vendor/ from scratch using gazelle

**What this PR does / why we need it**: the [godep `vendor/` instructions](https://github.com/kubernetes/community/blob/master/contributors/devel/godep.md) say to `rm -rf` everything under `vendor/` and then regenerate everything after saving. `gazelle` has slightly different functionality, in that it doesn't use `default_visibility`, which results in a large unrelated diff for anyone changing deps.

This PR regenerates everything in a no-op way so that subsequent changes have a reasonable diff.

Rerun init containers when the pod needs to be restarted

Whenever pod sandbox needs to be recreated, all containers associated
with it will be killed by kubelet. This change ensures that the init
containers will be rerun in such cases.

The change also refactors the compute logic so that the control flow of
init containers act is more aligned with the regular containers. Unit
tests are added to verify the logic.

This fixes #36485

Log name if Azure file share cannot be created

**What this PR does / why we need it**: If the Azure storage provider fails to create a file share, it logs and error message 'failed to create share in account _foo_: _error-msg_'.

This PR adds logging of the name so that this error can be diagnosed in future.

**Which issue this PR fixes**: This was raised on Slack and has not been created as a GitHub issue.

**Special notes for your reviewer**: None

**Release note**:

```release-note
Changed the error log format when creating an Azure file share to include the name of the share.

Resources outside the `*kubernetes.io` namespace are integers and cannot be over-committed.

Rationale: since the scheduler handles all resources except CPU as integers, that could just be the default behavior for namespaced resources.

Remove kubectl's dependence on schema file in pkg/api/validation.

**What this PR does / why we need it**:

Makes functions in validation/schema.go private to kubectl,
further isolating kubectl.  This move revealed a "hidden" dependence
(a dependence not expressed in a BUILD or make file) from a feature
level test in /hack/make-rules on a kubectl test data file.  So this
PR also adds some BUILD rules around the relevant hack targets, to make the
dependence official.  A later PR will move the kubectl aspect of this "hack"
test into a kubectl test directory.  Leaving it in place for now after establishing 
and "official" dependency, since moving the test beyond PR scope.  The
test also depends on a small sh file in //cluster, which makes no sense.

Fix for Policy based volume provisioning failure due to long VM Name in vSphere cloud provider

Dummy VM is used for SPBM policy based provisioning feature of vSphere cloud provider.
Dummy VM name is generated based on kubernetes cluster name and pv name. It can easily go beyond 
vSphere's limitation of 80 characters for vmName.

To solve the long VM name failure hash is used instead of vSphere-k8s-clusterName-PvName

Add metric for remaining lifetime of certificates authenticating requests

fixes #50778

When incoming requests to the API server are authenticated by a certificate, the expiration of the certificate can affect the validity of the authentication. With auto rotation of certificates, which is starting with kubelet certificates, the goal is to use shorter lifetimes and let the kubelet renew the certificate as desired. Monitoring certificates which are approaching expiration and not renewing would be an early warning sign that nodes are about to stop participating in the cluster.

**Release note**:

```release-note
Add new Prometheus metric that monitors the remaining lifetime of certificates used to authenticate requests to the API server.
