Adrian Reber f25770e48d Wire through CRI ContainerCheckpoint RPC
This connects the new CRI ContainerCheckpoint RPC to the existing
internal checkpoint functions. With this commit it is possible
to checkpoint a container in Kubernetes using the Forensic Container
Checkpointing KEP (#2008):

 # curl X POST "https://localhost:10250/checkpoint/namespace/podId/container"

Which will result in containerd creating a checkpoint in the location
specified by Kubernetes (usually /var/lib/kubelet/checkpoints).

This is a Linux only feature because CRIU only exists on Linux.

Rewritten with the help of Phil Estes.
