When starting pods or containers, we create the mount points
first. It seems natural to do something symetrical when stopping
pods or containers, i.e. removing the mount point at last.
Also, the current logic may not work with VM based containers as the
hypervisor may hold a reference on the mount point while we're trying to
remove them.

Use containers/storage to store images, pod sandboxes, and containers.
A pod sandbox's infrastructure container has the same ID as the pod to
which it belongs, and all containers also keep track of their pod's ID.
The container configuration that we build using the data in a
CreateContainerRequest is stored in the container's ContainerDirectory
and ContainerRunDirectory.
We catch SIGTERM and SIGINT, and when we receive either, we gracefully
exit the grpc loop. If we also think that there aren't any container
filesystems in use, we attempt to do a clean shutdown of the storage
driver.
The test harness now waits for ocid to exit before attempting to delete
the storage root directory.
