Synchronous & unbatched audit log writes
**What this PR does / why we need it**:
When enabling buffered audit log file writes to reduce latency under high load, we shouldn't be batching the writes, as the large data write can have an inverse (though unpredictable) impact. Additionally, batched audit log writes should not be done asynchronously, as this just creates lock contention on the log writer.

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.
