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.
```

Fixes for HTTP/2 max streams per connection setting
**What this PR does / why we need it**:
This PR makes two changes. One is to introduce a parameter
for the HTTP/2 setting that an api-server sends to its clients
telling them how many streams they may have concurrently open in
an HTTP/2 connection. If left at its default value of zero,
this means to use the default in golang's HTTP/2 code (which
is currently 250; see https://github.com/golang/net/blob/master/http2/server.go).
The other change is to make the recommended options for an aggregated
api-server set this limit to 1000. The limit of 250 is annoyingly low
for the use case of many controllers watching objects of Kinds served
by an aggregated api-server reached through the main api-server (in
its mode as a proxy for the aggregated api-server, in which it uses a
single HTTP/2 connection for all calls proxied to that aggregated
api-server).

**Special notes for your reviewer**:
**Release note**:
```release-note
Introduced `--http2-max-streams-per-connection` command line flag on api-servers and set default to 1000 for aggregated API servers.

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.

**What this PR does / why we need it**:
Makes the error message more descriptive and less scary. Previously it
is far from obvious whether connection kill is a symptom or cause of the
problem, see for example https://github.com/kubernetes/kubernetes/issues/55779#issuecomment-353582852
In paricular the crucial missing piece of information is that this is a
way of handling a timeout.

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
So we don't need this older style / hard coded / experimental code
anymore.
