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`.
A previous PR (https://github.com/kubernetes/kubernetes/pull/73726)
added GMSA support to the dockershim. Unfortunately, there was a
bug in there: the registry keys used to pass the cred specs down
to Docker were being cleaned up too early, right after the containers'
creation - before Docker would ever try to read them, when trying to
actually start the container.
This patch fixes this.
An e2e test is also provided in a separate PR.

This patch comprises the kubelet changes outlined in the GMSA KEP
(https://github.com/kubernetes/enhancements/blob/master/keps/sig-windows/20181221-windows-group-managed-service-accounts-for-container-identity.md)
to add GMSA support to Windows workloads.
More precisely, it includes the logic proposed in the KEP to resolve
which GMSA spec should be applied to which containers, and changes
`dockershim` to copy the relevant GMSA credential specs to Windows
registry values prior to creating the container, passing them down
to docker itself, and finally removing the values from the registry
afterwards; both these changes need to be activated with the `WindowsGMSA`
feature gate.
Includes unit tests.
