code-generator: unify generator main funcs and prepare for launching from one binary
- remove "generated by client-gen with custom arguments" message as this does not
make sense in the times of k8s.io/code-generator
- unify generator main funcs and explicitly call pflag.AddFlags and pflag.Parse. This
will allow to instantiate the generators also from other places.
Requires https://github.com/kubernetes/gengo/pull/80.
Closes https://github.com/kubernetes/kubernetes/issues/53522.

Fix a bug with exposing prometheus client metrics in multiple components
I think this is a bug caused by splitting the repos: prometheus metrics are registered in a module that initialized metrics client-go never uses.
```release-note
Fix a bug that prevents client-go metrics from being registered in prometheus in multiple components.

BuildConfigFromFlags function already calls the InClusterConfig()

There is a networking e2e test with the It() description:
```
"should provide unchanging, static URL paths for kubernetes api services"
```
This test performs GETs from the Kubernetes API using various paths,
including "/logs". This test for a GET using path "/logs" should be
skipped for provider type "skeleton", since this path is unsupported.
This change adds "skeleton" to the list of providers for which
this test case should be skipped.

Adjust defaults of audit webhook backends
This PR:
- increases the default buffer size to contain at lease on the order of magnitude audit events than it's possible to have simultaneous requests (500 AFAIR)
- increase the default batch size. From our load tests .95 size of the log entry is under 2.5KB, therefore 400 entry will sum up to ~1MB request, which sounds reasonable
- increase the initial backoff size. AFAIU, if the initial value is zero, all retries will be used in under 15 seconds (with 0.2 jitter and 1.5 factor), while the backend or a proxy can be unavailable for some reason for 30 seconds and more.
- add throttling to the batching audit webhook
A PR to make these parameters configurable will follow-up
@hzxuzhonghu implemented throttling part of this PR
```release-note
Adjust batching audit webhook default parameters: increase queue size, batch size, and initial backoff.
Add throttling to the batching audit webhook. Default rate limit is 10 QPS.

Move make clean to a static list
**What this PR does / why we need it**:
#51911 changed the functionality of `make clean` to use `git clean` to remove ignored files. This had unintended consequences, wiping things out like etcd. This changes it back to a static list, managed via a bash script. It's not optimal, but the static list of patterns is more up to date then it was keeping it in the make file.

Fixes the flaky TestDevicePluginReRegistration.
In the current test, there is a race that the new device plugin endpoint
may not be added to the device plugin manager endpoints at the time when
we call manager.Devices(). Added the checking and waiting for endpoint
updates before calling manager.Devices() in the test.
Tested:
go test -race -count 500 k8s.io/kubernetes/pkg/kubelet/deviceplugin -run
TestDevicePluginReRegistration -timeout 5h

Add group by default to kubeadm token create
Changes the default when creating tokens to include the group that is used during `kubeadm init`. The most likely use of this function is to create/recreate tokens to use with `kubeadm join` so let's make that a default.
fixes https://github.com/kubernetes/kubeadm/issues/483
```release-note
Change `kubeadm create token` to default to the group that almost everyone will want to use. The group is system:bootstrappers:kubeadm:default-node-token and is the group that kubeadm sets up, via an RBAC binding, for auto-approval (system:certificates.k8s.io:certificatesigningrequests:nodeclient).

Fix the version detection of OpenStack Cinder
**What this PR does / why we need it**:
When running Kubernetes against an installation of DevStack which
deploys the Cinder service at a path rather than a port (ex:
http://foo.bar/volume rather than http://foo.bar:xxx), the version
detection fails. It is better to use the OpenStack service catalog.
OTOH, when initialize cinder client, kubernetes will check the
endpoint from the OpenStack service catalog, so we can do this
version detection by it.
There are two case should be fixed in other PR:
1. revisit the version detection after supporting Cinder V3 API.
2. add codes to support MicroVersion after gophercloud supports MicroVersion.

Some of the environment variables have changed as devstack defaults
have changed. So look for the older env variables first and try the
newer ones later.
At a minimum you need the following for v3 authentication which is
the default with latest devstack. If you miss the Tenant information
then the token issued will be a unscoped token (and will not have any
service catalog information).

E2E test to verify clean up of stale dummy VM for vSphere dynamic provisioning
Verify if the dummy stale VM's created during dynamic provisioning are deleted by the clean up routine in vSphere cloud Provider.
**Testing Done:**
- Create a storage class with invalid policy on a VSAN datastore.
- Create a PVC using the above storage class
- Verify if the PVC is not bound.
- Delete the PVC.
- Sleep for 6 minutes so that vSphere Cloud Provider clean up routine can delete the stale dummy VM's.
- Verify if the VM is not present. Otherwise fail the test.
