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.

waitpid fills its second argument with a value that
contains the process exit code in the 8 least significant
bits. Instead of returning the complete value and then
convert it from ocid, return the exit status directly
by using WEXITSTATUS from conmon.

When we receive a SIGCHLD, log more information about how the child
processes that we reap terminated.

This lessens the Docker requirement for creating sandboxes (with the
requirement only existing for the actual image pulling that is done when
adding a container to a pod). The interface was chosen to match the
--conmon interface, so that the location of the pause binary can be
chosen by a user.
