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**:
