Allow nodes to create evictions for its own pods in NodeRestriction admission controller
**What this PR does / why we need it**: This PR adds support for `pods/eviction` sub-resource to the NodeRestriction admission controller so it allows a node to evict pods bound to itself.
**Which issue this PR fixes**: fixes#48666
**Special notes for your reviewer**: The NodeRestriction already allows nodes to delete pods bound to itself, so allowing nodes to also delete pods via the Eviction API probably makes sense.
```release-note
NodeRestriction allows a node to evict pods bound to itself
```
e2e and integration tests have been switched over to the tokenfile
authenticator instead.
```release-note
The --insecure-allow-any-token flag has been removed from kube-apiserver. Users of the flag should use impersonation headers instead for debugging.

Add RBAC v1beta1
Add `rbac.authorization.k8s.io/v1beta1`. This scrubs `v1alpha1` to remove cruft, then add `v1beta1`. We'll update other bits of infrastructure to code to `v1beta1` as a separate step.
```release-note
The `attributeRestrictions` field has been removed from the PolicyRule type in the rbac.authorization.k8s.io/v1alpha1 API. The field was not used by the RBAC authorizer.
