Detect long-running requests from parsed request info
Follow up to https://github.com/kubernetes/kubernetes/pull/36064
Uses parsed request info to more tightly match verbs and subresources
Removes regex-based long-running request path matching (which is easily fooled)
```release-note
The --long-running-request-regexp flag to kube-apiserver is deprecated and will be removed in a future release. Long-running requests are now detected based on specific verbs (watch, proxy) or subresources (proxy, portforward, log, exec, attach).

remove rbac super user
Cleaning up cruft and duplicated capabilities as we transition from RBAC alpha to beta. In 1.5, we added a secured loopback connection based on the `system:masters` group name. `system:masters` have full power in the API, so the RBAC super user is superfluous.
The flag will stay in place so that the process can still launch, but it will be disconnected.

etcd3: have prefix always prepended
ref: #36290
Previously, the prefix behavior is "sometimes prefixing". If the prefix already exists for the resource path, it will ignore.
With this PR, we make sure that prefix is always prepended in etcd3 storage backend. See the discussion in #36290
This removes all dependencies on Config during cert generation, only operating
on ServerRunOptions. This way we get rid of the repeated call of Config.Complete
and cleanly stratify the GenericApiServer bootstrapping.

plumb in front proxy group header
Builds on https://github.com/kubernetes/kubernetes/pull/36662 and https://github.com/kubernetes/kubernetes/pull/36774, so only the last commit is unique.
This completes the plumbing for front proxy header information and makes it possible to add just the front proxy header authenticator.
WIP because I'm going to assess it in use downstream.
