dpodctl - removal of volumes

This removes the volume management. Rather dpodctl exposes the single
volume into each container delegating to the setup to establish the
directory tree as necessary with proper permissions.

This also removes support for multiple setup sections.

In addition, TempMount is replaced by a boolean TmpMount that mounts /tmp
as tmpfs when given.
