Fixed minor issues.
Added missing template files.
Copied ControllerClientBuilder interface to cp.
This allows us to break the only dependency on K8s/K8s.

Fixed GoDeps.
Factored in feedback from JustinSB.
In the recent PR on adding ProcMount, we introduced a regression when
pods are privileged. This shows up in 18.06 docker with kubeadm in the
kube-proxy container.
The kube-proxy container is privilged, but we end up setting the
`/proc/sys` to Read-Only which causes failures when running kube-proxy
as a pod. This shows up as a failure when using sysctl to set various
network things.

This change adds comments to exported things and renames the tcp,
http, and exec probe interfaces to just be Prober within their
namespace.

add missing LastTransitionTime of ContainerReady condition
```
We are removing dependencies on docker types where possible in the core
libraries. credentialprovider is generic to Docker and uses a public API
(the config file format) that must remain stable. Create an equivalent type
and use a type cast (which would error if we ever change the type) in the
dockershim. We already perform a transformation like this for CRI and so
we aren't changing much.

Consolidate componentconfig code standards
**What this PR does / why we need it**:
This PR fixes a bunch of very small misalignments in ComponentConfig packages:
- Add sane comments to all functions/variables in componentconfig `register.go` files
- Make the `register.go` files of componentconfig pkgs follow the same pattern and not differ from each other like they do today.
- Register the `openapi-gen` tag in all `doc.go` files where the pkg contains _external_ types.
- Add the `groupName` tag where missing
- Fix cases where `addKnownTypes` was registered twice in the `SchemeBuilder`
- Add `Readme` and `OWNERS` files to `Godeps` directories if missing.

fix token controller keyFunc bug
Currently, token manager use keyFunc like: `fmt.Sprintf("%q/%q/%#v", name, namespace, tr.Spec)`.
Since tr.Spec contains point fields, new token request would not reuse the cache at all.

CSI Cluster Registry and Node Info CRDs
**What this PR does / why we need it**:

**Special notes for your reviewer**:
Per the discussion in https://groups.google.com/d/msg/kubernetes-sig-storage-wg-csi/x5CchIP9qiI/D_TyOrn2CwAJ the API is being added to the staging directory of the `kubernetes/kubernetes` repo because the consumers will be attach/detach controller and possibly kubelet, but it will be installed as a CRD (because we want to move in the direction where the API server is Kubernetes agnostic, and all Kubernetes specific types are installed).
**Release note**:
```release-note
Introduce CSI Cluster Registration mechanism to ease CSI plugin discovery and allow CSI drivers to customize Kubernetes' interaction with them.
```

Add a ProcMount option to the SecurityContext & AllowedProcMountTypes to PodSecurityPolicy
So there is a bit of a chicken and egg problem here in that the CRI runtimes will need to implement this for there to be any sort of e2e testing.
**What this PR does / why we need it**: This PR implements design proposal https://github.com/kubernetes/community/pull/1934. This adds a ProcMount option to the SecurityContext and AllowedProcMountTypes to PodSecurityPolicy
Relies on https://github.com/google/cadvisor/pull/1967
**Release note**:
```release-note
ProcMount added to SecurityContext and AllowedProcMounts added to PodSecurityPolicy to allow paths in the container's /proc to not be masked.

wait until apiserver connection before starting kubelet tls bootstrap
I wonder if this helps with sometimes slow network programming
cc @mwielgus @awly
This vendor change was purely for the changes in docker to allow for
setting the Masked and Read-only paths.
See: moby/moby#36644
But because of the docker dep update it also needed cadvisor to be
updated and winterm due to changes in pkg/tlsconfig in docker

Honor --hostname-override, report compatible hostname addresses with cloud provider
xref #677147828e5d made cloud providers authoritative for the addresses reported on Node objects, so that the addresses used by the node (and requested as SANs in serving certs) could be verified via cloud provider metadata.
This had the effect of no longer reporting addresses of type Hostname for Node objects for some cloud providers. Cloud providers that have the instance hostname available in metadata should add a `type: Hostname` address to node status. This is being tracked in #67714
This PR does a couple other things to ease the transition to authoritative cloud providers:
* if `--hostname-override` is set on the kubelet, make the kubelet report that `Hostname` address. if it can't be verified via cloud-provider metadata (for cert approval, etc), the kubelet deployer is responsible for fixing the situation by adjusting the kubelet configuration (as they were in 1.11 and previously)
* if `--hostname-override` is not set, *and* the cloud provider didn't report a Hostname address, *and* the auto-detected hostname matches one of the addresses the cloud provider *did* report, make the kubelet report that as a Hostname address. That lets the addresses remain verifiable via cloud provider metadata, while still including a `Hostname` address whenever possible.
