Migrate to cobra CLI

We intend to migrate to the cobra cli from urfave/cli because the
project is more well maintained.  There are also some technical reasons
as well which extend into our remote client work.

 Container storage increments a mount counter each time a container is mounted.
 When a container is unmounted, the mount counter is decremented and the
 container's root filesystem is physically unmounted only when the mount
 counter reaches zero indicating no other processes are using the mount.
 An unmount can be forced with the --force flag.
