Make kubectl proxy accept empty path
**What this PR does / why we need it**:
The kubectl proxy previously returned 403 Forbidden: Unauthorized when receiving a request from e.g. "curl localhost:8001" or "curl localhost:8001/". The previous DefaultPathAcceptRE regex was wrong as it assumed the path in this case would be "/" (but it is actually "").
After someone runs kubectl proxy and tries accessing it with curl, they will probably just try hitting localhost:8001 (which returns an "Unauthorized" response) instead of say localhost:8001/api (which returns a proper response from the API server). Also, whoever previously modified the DefaultPathAcceptRE regex was obviously expecting the regex to accept requests for localhost:8001/
```release-note
fix issue with kubectl proxy so that it will proxy an empty path - e.g. http://localhost:8001
```

Bugfix on kubeadm join with non-token discovery.

Remove RBAC UserAll
* Removes special handling of User * subjects in rolebinding matching evaluation
* Converts v1alpha1 rolebindings to `User *` subjects to `Group system:authenticated` subjects for backwards compatibility
```release-note
RBAC's special handling of the User subject named "*" in RoleBinding and ClusterRoleBinding objects is being deprecated and will be removed in v1beta1. Existing v1alpha1 role bindings to User "*" will be converted to the group "system:authenticated". To match unauthenticated requests, RBAC role bindings must explicitly bind to the group "system:unauthenticated".

Ensure invalid token returns 401 error, not 403
fixes#39267
If a user attempts to use a bearer token, and the token is rejected, the authenticator should return an error. This distinguishes requests that did not provide a bearer token (and are unauthenticated without error) from ones that attempted to, and failed.

snip links from genericapiserver to api/validation
We had a trip dependency on `pkg/api/validation` through `pkg/api/rest` which is used for RESTStorage. This splits the generic validation required for a genericapiserver out from the rest of validation. For now, functions still delegate.

Start moving genericapiserver to staging
This moves `pkg/auth/user` to `staging/k8s.io/genericapiserver/pkg/authentication/user`. I'll open a separate pull into the upstream gengo to support using `import-boss` on vendored folders to support staging.
After we agree this is the correct approach and see everything build, I'll start moving other packages over which don't have k8s.io/kubernetes deps.

make discovery static when extensions/thirdpartyresources is not enabled
this should be a bug fix, if `extensions/thirdpartyresources` is enabled, the result of `Discovery().ServerPreferredNamespacedResources` will be dynamic then, so we are making the `discoverResourcesFn` static only when the `extensions/thirdpartyresources` is not enabled.

Small improve for GetContainerOOMScoreAdjust
In `GetContainerOOMScoreAdjust`, make logic more clear for the case `oomScoreAdjust >= besteffortOOMScoreAdj`. If `besteffortOOMScoreAdj` is defined to another value(e.g. 996), suppose `oomScoreAdjust` is 999, the function will return 998(which equals 999 - 1) instead of 995(996 -1).

oidc auth-n plugin: enforce email_verified claim
This change causes the OpenID Connect authenticator to start
enforcing the 'email_verified' claim.
https://openid.net/specs/openid-connect-core-1_0.html#StandardClaims
If the OIDC authenticator uses the 'email' claim as a user's username
and the 'email_verified' is not set to `true`, reject that authentication attempt.
cc @erictune @kubernetes/sig-auth @mlbiam
```release-note
When using OIDC authentication and specifying --oidc-username-claim=email, an `"email_verified":true` claim must be returned from the identity provider.

Remove needless env var in OpenStack provider
**What this PR does / why we need it**:
If we use openstack provider to set up k8s cluster using kube-up script,
`TENANT_ID` environment variable is needed.
But to configure `TENANT_ID` is very annoying because this value is not static by each env.
This patch uses `TENANT_NAME` instead of `TENANT_ID`
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
**Special notes for your reviewer**:
**Release note**:
```release-note
```
Since `TENANT_NAME` is unique if we use keystone v2 api,
so `TENANT_ID` is not needed if `TENANT_NAME` is provided
to configure OpenStack provider.
And also to set `TENANT_ID` is annoying to develop, because
`TENANT_ID` is not static by each environment.
This patch remove dependency of `TENANT_ID` and simply use
`TENANT_NAME`.

Moves e2e service util functions into service_util.go and cleans up
Basically moves codes into a central place for service util functions.
Some other codes are touched mostly only due to this migration. Also put a bunch of network reachability utils functions into network_utils.go. They seem somehow redundant, may consider combine they later.
