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).
