Create volumeMount and hostPath for cloud config file
We have a way to specify the cloudProvider in kubeadm.conf. We also
add `--cloud-config /etc/kubernetes/cloud-config` to both the
kubernetes api server and controller manager yaml files if one exists
on the box. However we fail to make that file available to the
process running in the container. We need to make this `cloud-config`

Add brackets around IPv6 kube-dns liveness probe addrs
**What this PR does / why we need it**:
Previously, when an IPv6-only Kubernetes cluster was instantiated
via 'kubeadm init ...', the liveness probes that were
configured by kubeadm for kube-dns currently use IP:port
strings of "::1:53" and "::1:10053". These IP:port strings should
instead include brackets around the ::1 IPv6 loopback address, e.g.
"[::1]:53" and "[::1]:10053".
This change adds the necessary brackets around the ::1 IPv6 loopback
address.
Without this change, the kube-dns sidecar container interprets the
bracket-less strings as IPv4 IP:port strings that have too many
colons, and the kube-dns pod is restarted about once every 2 minutes.

fluend-gcp already has these tolerations. kube-proxy when it runs as a
static pod gets wildcard `NoExecute` toleration (all static pods get
that). So, added the same toleration to kube-proxy when it runs as a
daemonset. Also added wildcard `NoSchedule` toleration to kube-proxy.
We have a way to specify the cloudProvider in kubeadm.conf. We also
add `--cloud-config /etc/kubernetes/cloud-config` to both the
kubernetes api server and controller manager yaml files if one exists
on the box. However we fail to make that file available to the
process running in the container. We need to make this `cloud-config`
file available to both processes similar to how controller-manager.conf
is passed to controller manager.
It is expected that nodes with extended resources attached will be
tainted with the resouce name, so that we can create dedicated nodes.
If ExtendedResourceToleration admission controller is enabled, pods
requesting such resources will automatically tolerate such taints.
nvidia-gpu-device-plugin daemonset doesn't request such resources but
still needs to run on such nodes, so it needs this toleration.
When a Kubernetes cluster is instantiated in IPv6-only mode
via 'kubeadm init ...', the liveness probes that are
configured by kubeadm for kube-dns currently use IP:port
strings of "::1:53" and "::1:10053". These IP:port strings should

This change adds the necessary brackets around the ::1 IPv6 loopback

[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.
