Fix autoscaling API documentation
**What this PR does / why we need it**:
This PR fixes the API documentation generated for HorizontalPodAutoscaler resource.
**Which issue(s) this PR fixes**:
The current API doc for `MetricSpec` and `MetricStatus` is confusing. Users get no idea what can be used as the value for the `type` field, because the doc says this:
```
type is the type of metric source. It should match one of the fields below.
```
While acceptable in the source code, it makes no senses when reading the API doc, especially when the "`type`" field is listed as the last row in a table (see: https://kubernetes.io/docs/api-reference/v1.8/#metricspec-v2beta1-autoscaling )
**Special notes for your reviewer**:
This PR makes no changes to the code behavior.

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.

Support autoprobing floating-network-id for openstack cloud provider
Currently if user doesn't specify floatingnetwork-id and loadbalancer.openstack.org/floating-network-id annotation, openstack cloud provider can't create a external LoadBalancer service.
Actually we can get floatingnetwork-id automatically.
If we get multiple floatingnetwork-ids, then ask user to specify one, or we use the floatingnetwork-id to create floatingip for external LoadBalancer service.
This is a part of #50726

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.

Document None dns policy clearly
**What this PR does / why we need it**:

Return original error instead of negotiation one
**What this PR does / why we need it**:
When the requested type (eg. `text/html`) is not available and we're trying to hit an endpoint to which a user is for unauthorized we'll get 406, instead of 403. The reason for that is that, even if error happens we're trying to match the serializer, which fails and results in swallowing error, instead of returning raw json, for example.
This fix returns raw json for such situations.
