e10042d22f Increment CRI version from v1alpha1 to v1alpha2
This also incorporates the version string into the package name so
that incompatibile versions will fail to connect.

Arbitrary choices:
- The proto3 package name is runtime.v1alpha2. The proto compiler
  normally translates this to a go package of "runtime_v1alpha2", but
  I renamed it to "v1alpha2" for consistency with existing packages.
- kubelet/apis/cri is used as "internalapi". I left it alone and put the
  public "runtimeapi" in kubelet/apis/cri/runtime.

Set ExecSync timeout in liveness prober.

Although Dockershim doesn't actually support `ExecSync` timeout (see [here](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/dockershim/exec.go#L137)), we should set the timeout, so that the other runtime which supports the timeout could work properly.

Fixes #50389.

Add UpdateContainerResources method to CRI

This is first step toward support for opinionated cpu pinning for certain guaranteed pods.

In order to do this, the kubelet needs to be able to dynamically update the cpuset at the container level, which is managed by the container runtime.  Thus the kubelet needs a method to communicate over the CRI so the runtime can then modify the container cgroup.

This is used in the situation where a core is added or removed from the shared pool to become a exclusive core for a new G pod.  The cpuset for all containers in the shared pool will need to be updated to add or remove that core.

Opening this up now so we can start discussion.  The need for a change to the CRI might be unexpected.

CRI: add methods for container stats

**What this PR does / why we need it**:
Define methods in CRI to get container stats.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: 
Part of  https://github.com/kubernetes/features/issues/290; addresses #27097

**Special notes for your reviewer**:
This PR defines the *minimum required* container metrics for the existing components to function, loosely based on the previous discussion on [core metrics](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/core-metrics-pipeline.md) as well as the existing cadvisor/summary APIs.
 
Two new RPC calls are added to the RuntimeService: `ContainerStats` and `ListContainerStats`. The former retrieves stats for a given container, while the latter gets stats for all containers in one call.
 
The stats gathering time of each subsystem can vary substantially (e.g., cpu vs. disk), so even though the on-demand model preferred due to its simplicity, we’d rather give the container runtime more flexibility to determine the collection frequency for each subsystem*. As a trade-off, each piece of stats for the subsystem must contain a timestamp to let kubelet know how fresh/recent the stats are. In the future, we should also recommend a guideline for how recent the stats should be in order to ensure the reliability (e.g., eviction) and the responsiveness (e.g., autoscaling) of the kubernetes cluster.
 
The next step is to plumb this through kubelet so that kubelet can choose consume container stats from CRI or cadvisor. 
 
**Alternatively, we can add calls to get stats of individual subsystems. However, kubelet does not have the complete knowledge of the runtime environment, so this would only lead to unnecessary complexity in kubelet.*


**Release note**:

```release-note
Augment CRI to support retrieving container stats from the runtime.
```

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**:
