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`
file available to both processes similar to how controller-manager.conf
is passed to controller manager.

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.

Allow config and ignore-preflight to be specified together
In commit 3a0aa06fc9, the flag
was changed from `ignore-checks-errors` to `ignore-preflight-errors`,
but the condition check in ValidateMixedArguments was not updated.
So specifying say `--config kubeadm.conf --ignore-preflight-errors all`
would fail.

[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.

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.

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.
