This patch makes the CRI `v1` API the new project-wide default version.
To allow backwards compatibility, a fallback to `v1alpha2` has been added
as well. This fallback can either used by automatically determined by
the kubelet.

As the final step, add the `dockerless` tags to all files in the
dockershim. Using `-tags=dockerless` in `go build`, we can compile
kubelet without the dockershim.
Once cadvisor no longer depends on `docker/docker`, compiling with
`-tags=dockerless` should be sufficient to compile the Kubelet w/o a
dependency on `docker/docker`.
docker folks added NumCPU implementation for windows that
supported hot-plugging of CPUs. The implementation used the
GetProcessAffinityMask to be able to check which CPUs are
active as well.

The golang "runtime" package has also bene using GetProcessAffinityMask
since 1.6 beta1:

So we don't seem to need the sysinfo.NumCPU from docker/docker.
(Note that this is PR is an effort to get away from dependencies from
docker/docker)

- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

Windows supports both sandbox and non-sandbox cases. The non-sandbox
case is for Windows Server 2016 and for Windows Server version greater
than 1709 which use Hyper-V containers.
Currently, the CNI on Windows fetches the IP from the containers
within the pods regardless of the mode. This should be done only
in the non-sandbox mode where the IP of the actual container
will be different than the IP of the sandbox container.
In the case where the sandbox container is supported, all the containers
from the same pod will share the network details of the sandbox container.
This patch updates the CNI to fetch the IP from the sandbox container
when this mode is supported.

Currently the Windows Server 2016 RTM has no CNI support.
With this commit, the Windows Server 2016 RTM will be able
to use the CNI plugin for networking setup.
This commit also moves some comments to the right place.

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.

Following are part of this commit
+++++++++++++++++++++++++++++++++
* Windows CNI Support
(1) Support to use --network-plugin=cni
(2) Handled platform requirement of calling CNI ADD for all the containers.
(2.1) For POD Infra container, netNs has to be empty
(2.2) For all other containers, sharing the network namespace of POD container,
should pass netNS name as "container:<Pod Infra Container Id>", same as the
NetworkMode of the current container
(2.3) The Windows CNI plugin has to handle this to call into Platform.
Sample Windows CNI Plugin code to be shared soon.
* Sandbox support for Windows
(1) Sandbox support for Windows. Works only with Docker runtime.
(2) Retained CONTAINER_NETWORK as a backward compatibilty flag,
to not break existing deployments using it.
(3) Works only with CNI plugin enabled.
(*) Changes to reinvoke CNI ADD for every new container created. This is hooked up with PodStatus,
but would be ideal to move it outside of this, once we have CNI GET support
