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.

Introduce PodSecurityPolicy in the policy/v1beta1 API group
Types/constants are completely the same as in `extensions/v1beta1` except that they are located outside of the `extensions` API group.
**What this PR does / why we need it**:
This is the first step for migrating PSP-related stuff away of `extensions` group. See #43214 for more information.
Also it related to https://github.com/kubernetes/features/issues/5
**Example**:
```console
$ cat restricted2.yaml
apiVersion: policy/v1beta1
kind: PodSecurityPolicy
metadata:
name: restricted2
...
$ kubectl create -f restricted.yaml
podsecuritypolicy "restricted2" created
$ kubectl get psp restricted2 -o yaml
apiVersion: extensions/v1beta1
kind: PodSecurityPolicy
...
```
**Release note**:
```release-note
The `PodSecurityPolicy` API has been moved to the `policy/v1beta1` API group. The `PodSecurityPolicy` API in the `extensions/v1beta1` API group is deprecated and will be removed in a future release.

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:
a0cebcb559
So we don't need this older style / hard coded / experimental code
anymore.

WIP, assign to myself first
/assign @NickrenREN
Right now if a JWT for an unknown issuer, for any subject hits the
serviceaccount token authenticator, we return a errors as if the token
was meant for us but we couldn't find a key to verify it. We should
instead return nil, false, nil.
This change helps us support multiple service account token
authenticators with different issuers.

expose special storage locations for downstream consumption
Storage locations are public information and needed for congruent storage. This exposes them in their new home.
As part of the larger plan to drop --cloud-provider and --cloud-config
from kube-apiserver, we need to stop calling Cloud Provider API to
find the external ip address when one is not specified on the command
line.
When ExternalHost is not specified, we check if AdvertiseAddress is
specified and use that, if that is missing then we use os.Hostname().
When testing this feature, found a problem that when ExternalHost
is specified, the port was not added in the generated URL. So fixed
that as well.

apiserver: pass a listener into genericapiserver bootstrapping
**What this PR does / why we need it**:
>At the moment we pass a port via the options into the config. A zero port does not work because the loopback clients created during apiserver initialization need to know the port before. Passing a listener into the server instead would allow us to use a zero port beforehand and bootstrapping order should be fine.
