Integrate containers/storage

Browse source 
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.
