ceph-volume: implement the 'lvm batch' subcommand

This adds the action 'batch' to the ceph-volume module so that we can
run the new 'ceph-volume lvm batch' subcommand. A functional test is
also included.

If devices is defind and osd_scenario is lvm then the 'ceph-volume lvm
batch' command will be used to create the OSDs.
