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.

[Test Fix] Fake docker client can remove containers which have not been started
**What this PR does / why we need it**:
During kubemark-5000 scalability tests, which use the fake docker client, we encountered a bug where containers where the pod was deleted before the container was started could not be deleted.
This is because we only remove pods from the `ExitedContainers` list. Containers are only added to this when they have been created, started, and then stopped. However, containers that have only been created, but not started cannot be deleted. This PR fixes this issue by allowing containers with `State.Running=false` to be deleted.

kube-apiserver: enable admissionregistration v1beta1 api by default
We have this enabled in the GCE cluster and in local-cluster-up, but forgot to switch the default. If we want people to use this feature by default in production clusters, we better enable the API.
Moreover, this PR fixes that beta works without alpha.

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

[Test Fix] Mock docker network dependencies and fix filtering bug
This PR only affects the mocked docker runtime, and has no impact on the kubelet.
Issue #53327
When kubernetes creates a pod using the docker shim, it creates a container which contains the pod's network namespace, and then creates containers which specify that namespace.
The current mocked docker does not mock this interaction, and thus allows a container to be created even when the container whose network it is joining does not exist.
This allows the mocked kubelet to end up in a state where the pod does not exist, but a container in the pod does, and this breaks pod deletion.
This fixes the above by only allowing containers to be started if the container whose network it is trying to join is running.
Additionally, this PR fixes a filtering bug where we were incorrectly comparing docker container statuses.

This PR implement a new priority function `ResourceLimitsPriorityMap` (disabled by default and behind alpha feature gate and not part of the scheduler's default priority functions list) that assigns a lowest possible score of 1 to a node that satisfies one or both of input pod's cpu and memory limits, mainly to break ties between nodes with same scores.

fix network value for stats summary for multiple network interfaces
This PR is part of [Heapster #1788](https://github.com/kubernetes/heapster/pull/1788).
The original reason is when there are more than one none `lo`, `docker0`, `veth` network interfaces instead of just one `eth0`, the network interface value is only partial and does not correct. For now, summary stats api only gets the eth0 network interface values.
The original issues about this can be find in [Heapster #1058](https://github.com/kubernetes/heapster/issues/1058) and [Cadvisor #1593](https://github.com/google/cadvisor/issues/1593).

Fix GC sync race condition
Remove faulty diff detection logic from GC sync which leads to a race
condition: If the GC's discovery client is returning a fully up to date
view of server resources during the very first GC sync, the sync
function will never sync monitors or reset the REST mapper unless
discovery changes again. This causes REST mapping to fail for any custom
types already present in discovery.
