Separate loop and plugin control
**What this PR does / why we need it**: Separate loop and plugin control in the kube-controller-manager.
Adding an "--external-plugin" flag to specify a plugin to load when

that the cloud provider and external plugin flags would go away once
all cloud providers are on stage 2 cloud-controller-manager solutions.

As part of the larger plan to drop --cloud-provider and --cloud-config
from kube-apiserver, we need to stop calling Cloud Provider API to
find the external ip address when one is not specified on the command
line.
When ExternalHost is not specified, we check if AdvertiseAddress is
specified and use that, if that is missing then we use os.Hostname().
When testing this feature, found a problem that when ExternalHost
is specified, the port was not added in the generated URL. So fixed
that as well.

Make audit batch webhook backend configurable
This PR adds an ability to configure key parameters for the most important audit backend at-scale, so that if the default parameters don't fit and audit events are lost/delayed, it's possible to adjust these parameters to fix the problem. In the future those parameters will stay, but will be used to populate the values for the generic buffering backend, both for webhook and log backends.
/cc @kubernetes/sig-auth-pr-reviews @sttts @tallclair @ericchiang
```release-note
Audit webhook batching parameters are now configurable via command-line flags in the apiserver.
