Remove dep-reviewers
**What this PR does / why we need it**:
The dep-reviewers group seems to get assigned PRs early the the review process. However, most code changes should be reviewed in the importing part of the code base first, and then assigned to an approver after.
By removing the reviewers group, the approvers plugin will still suggest assigning to an approver, but won't assign for review when the PR is initially opened.

Serve OpenAPI spec with single /openapi/v2 endpoint
**What this PR does / why we need it**:
We are deprecating format-separated endpoints (`/swagger.json`, `/swagger-2.0.0.json`, `/swagger-2.0.0.pb-v1`, `/swagger-2.0.0.pb-v1.gz`) for OpenAPI spec, and switching to a single `/openapi/v2` endpoint in Kubernetes 1.10. The design doc and deprecation process are tracked at: https://docs.google.com/document/d/19lEqE9lc4yHJ3WJAJxS_G7TcORIJXGHyq3wpwcH28nU
Requested format is specified by setting HTTP headers
header | possible values
-- | --
Accept | `application/json`, `application/com.github.proto-openapi.spec.v2@v1.0+protobuf`
Accept-Encoding | `gzip`
This PR changes dynamic_client (and kubectl as a result) to use the new endpoint. The old endpoints will remain in 1.10 and 1.11, and get removed in 1.12.

Introduce buffered audit backend
This is a copy from https://github.com/kubernetes/kubernetes/issues/53006 with comments addressed, since @hzxuzhonghu cannot work on this right now and the code freeze is close. Thanks @hzxuzhonghu for the contribution!
This is the first PR to fix https://github.com/kubernetes/kubernetes/issues/53006 and then https://github.com/kubernetes/kubernetes/issues/53020
This PR introduces a new audit backend, that batches incoming audit events and sends these batches to the underlying audit backend. This new backend is designed to replace existing batching webhook backend and allow to use batching with log backend, to solve the performance issues.
@sttts @ericchiang @CaoShuFeng @tallclair would really appreciate your review
```release-note
Buffered audit backend is introduced, to be used with other audit backends.

oidc authentication: switch to v2 of coreos/go-oidc
Switch to v2 of [coreos/go-oidc](https://github.com/coreos/go-oidc), which uses square/go-jose to verify tokens and supports more signing algorithms.
Most of this PR removes dependencies used by the older version of github.com/coreos/go-oidc, and updates vendor files.
This PR has been tested against tokens issued by Okta, Google, and CoreOS's dex.
Closes https://github.com/kubernetes/kubernetes/issues/57806
```release-note
kube-apiserver: the OpenID Connect authenticator can now verify ID Tokens signed with JOSE algorithms other than RS256 through the --oidc-signing-algs flag.
kube-apiserver: the OpenID Connect authenticator no longer accepts tokens from the Google v3 token APIs, users must switch to the "https://www.googleapis.com/oauth2/v4/token" endpoint.

Remove experimental keystone authenticator
**What this PR does / why we need it**:
experimental-keystone-url and experimental-keystone-ca-file were always
experimental. So we don't need a deprecation period.
KeystoneAuthenticator was on the server side and needed userid/password
to be passed in and used that to authenticate with Keystone. We now
have authentication and authorization web hooks that can be used. There
is a external repo with a webook for keystone which works fine along
with the kubectl auth provider that was added in:
a0cebcb559c5c0ab8a2e50b1ee11cc62f9ebb3a8

Promote v1alpha1 meta to v1beta1
No code changes, just renames. We can discuss if there are any field / naming changes here or in a follow-up

Prereq to #55637
@kubernetes/sig-api-machinery-pr-reviews @deads2k
```release-note
The `meta.k8s.io/v1alpha1` objects for retrieving tabular responses from the server (`Table`) or fetching just the `ObjectMeta` for an object (as `PartialObjectMetadata`) are now beta as part of `meta.k8s.io/v1beta1`. Clients may request alternate representations of normal Kubernetes objects by passing an `Accept` header like `application/json;as=Table;g=meta.k8s.io;v=v1beta1` or `application/json;as=PartialObjectMetadata;g=meta.k8s.io;v1=v1beta1`. Older servers will ignore this representation or return an error if it is not available. Clients may request fallback to the normal object by adding a non-qualified mime-type to their `Accept` header like `application/json` - the server will then respond with either the alternate representation if it is supported or the fallback mime-type which is the normal object response.

flag precedence redo
Changes the Kubelet configuration flag precedence order so that flags take precedence over config from files/ConfigMaps.
This should fix the re-parse issue with #56097 that led to revert.
Fixes#56171.
In order to prevent global flags (registered in 3rd party libs, etc.) from leaking into the command's help text, this PR turns off Cobra's flag parsing in the `kubelet` command and re-implements help and usage funcs for the Kubelet. Cobra's default funcs automatically merge all global flags into the command's flagset, which results in incorrect help text. I tried to keep the formatting as close as possible to the what the Kubelet currently produces.
Diff between Kubelet's help text on `upstream/master` vs `mtaufen/kc-flags-precedence-redo`, which shows a leaked flag being removed, but no change to the formatting:

Ultimately, I think we should implement a common lib that K8s components can use to generate clean help text, as the global flag leakage problem affects all core k8s binaries. I would like to do so in a future PR, to keep this PR simple. We could base the help text format on the default values returned from `Command.HelpTemplate` and `Command.UsageTemplate`. Unfortunately, the template funcs used to process these defaults are private to Cobra, so we'd have to re-implement these, or avoid using them.

Add a metric to track usage of inflight request limit.
This one is tricky. The goal is to know how 'loaded' given apiserver is before we start dropping the load, to so we need to somehow expose 'fullness' of channels.
Sadly this metric is pretty volatile so it's not clear how to do this correctly. I decided to do pre-aggregation to smoothen the metric a bit. In the current implementation the metric publishes maximum "usage" of the inflight is previous second.
If you have any ideas please share.

Resource version parsing should all be in one place
This is 100% refactoring that ought to be a no-op at run time. It puts resource version parsing in a single file. Doing this because I want to follow up with a change which will make it obvious to users of the system our rules about resource version. Don't want to mix that with this refactor (on the off chance it gets rolled back).

Never let cluster-scoped resources skip webhooks
Fix#57964
This allows user write webhooks for cluster-scoped custom resources.
We still need to figure out how to selectively exempt cluster-scoped resources from webhooks to avoid bootstrapping deadlocks. For now, if a deadlock occurs, users can work around by first deleting the webhook configuration, then rebooting the webhook, then re-enabling the webhook configuration.
```release-note
Bug fix: webhooks now do not skip cluster-scoped resources
Action required: Before upgrading your Kubernetes clusters, double check if you had configured webhooks for cluster-scoped objects (e.g., nodes, persistentVolume), these webhooks will start to take effect. Delete/modify the configs if that's not desirable.

don't stop informer delivery on error
If an informer delivery fails today, we stop delivering to it entirely. The pull updates the code to skip that particular notification, delay, and continue delivery with the next time.
