Support TCP type runtime endpoint for kubelet
**What this PR does / why we need it**:
Currently the grpc server for kubelet and dockershim has a hardcoded endpoint: unix socket '/var/run/dockershim.sock', which is not applicable on non-unix OS.
This PR is to support TCP endpoint type besides unix socket.
**Which issue this PR fixes**
This is a first attempt to address issue https://github.com/kubernetes/kubernetes/issues/45927
**Special notes for your reviewer**:
Before this change, running on Windows node results in:
```
Container Manager is unsupported in this build
```
After adding the cm stub, error becomes:
```
listen unix /var/run/dockershim.sock: socket: An address incompatible with the requested protocol was used.
```
This PR is to fix those two issues.
After this change, still meets 'seccomp' related issue when running on Windows node, needs more updates later.
**Release note**:
Some imports dont exist yet (or so it seems) in client-go (examples
being:
- "k8s.io/kubernetes/pkg/api/validation"
- "k8s.io/kubernetes/pkg/util/initsystem"
- "k8s.io/kubernetes/pkg/util/node"
one change in kubelet to import to client-go
We had another bug where we confused the hostname with the NodeName.
To avoid this happening again, and to make the code more
self-documenting, we use types.NodeName (a typedef alias for string)
whenever we are referring to the Node.Name.
A tedious but mechanical commit therefore, to change all uses of the
node name to use types.NodeName
Also clean up some of the (many) places where the NodeName is referred
to as a hostname (not true on AWS), or an instanceID (not true on GCE),
etc.
Including `cmd/kubelet/app` in kubeadm causes flag leakage.
Namelly, the problem is with `pkg/credentialprovider/gcp`, which
leaks `--google-json-key` and changing the behaviour of `init()`
doesn't sound reasonable, given kubelet is the only one who uses
this packages and obviously the flag is part of the functionality.
The helper is already generic enough, it has already been exported
and works well for kubeadm, so moving it should be fine.

Remove RunInContainer interface in Kubelet Runtime interface
According to #24689, we should merge RunInContainer and ExecInContainer in the container runtime interface.

Add utility for kubelet to log resource lists consistently
This is a simple utility for logging resource lists with standardized output.
I find it useful when logging work in node eviction, similar to kubelet logging convention for pods in same package.
