apiserver: make loopback logic in SecureServingOptions reusable
For reuse in other components this PR separates the loopback logic from the GenericApiServer config.
Before this the advertised IP (which shows up in the server cert) in case of
listening to loopback was the first host interface IP. This makes self-signed
certs non-constant, such that we cannot use fixtures.

The goal of this change is to remove the registration of signal
handling from pkg/kubelet. We now pass in a stop channel.
If you register a signal handler in `main()` to aid in a controlled
and deliberate exit then the handler registered in `pkg/kubelet` often
wins and the process exits immediately. This means all other signal
handler registrations are currently racy if `DockerServer.Start()` is
directly or indirectly invoked.
This change also removes another signal handler registration from
`NewAPIServerCommand()`; a stop channel is now passed to this
function.

Re-enable lease reconciler, fix shutdown race
Fixes#63378Fixes#57617
* Fixes the openapi script to wait for the apiserver on shutdown (like all the other scripts do)
* Fixes the apiserver shutdown to not hang forever if the kubernetes service reconciler cannot persist to etcd
* Readds https://github.com/kubernetes/kubernetes/pull/58474 to make the default the lease reconciler
```release-note
kube-apiserver: the default `--endpoint-reconciler-type` is now `lease`. The `master-count` endpoint reconciler type is deprecated and will be removed in 1.13.

Remove request context mapper
http.Request now allows setting/retrieving a per-request context, which removes the need for plumbing a request-context mapper throughout the stack
In addition to being way simpler, this has the benefit of removing a potentially contentious lock object from the handling path
This PR:
* removes RequestContextMapper
* converts context fetchers to use `req.Context()`
* converts context setters to use `req = req.WithContext(...)`
* updates filter plumbing in two places (audit and timeout) to properly return the request with modified context
* updates tests that used a fake context mapper to set the context in the request instead
Fixes https://github.com/kubernetes/kubernetes/issues/62796
```release-note

This change updates the REST mapper used by all admission plugins to
be backed by cached discovery information. This cache is updated
every ten seconds via a post start hook and will not attempt to
update on calls to RESTMapping. It solely relies on the hook to
keep the cache in sync with discovery.
This prevents issues with the OwnerReferencesPermissionEnforcement
admission plugin when it is used with custom resources that set
blockOwnerDeletion.
