Konrad Sztyber 64fe514efa bdev/ocssd: parallel unit ranges
This patch adds the ability to create bdevs on specified parallel unit
ranges on one OCSSD controller.  It allows the user to create multiple
isolated bdevs, each operating on a separate set of parallel units.

To create a bdev on a specified range, a new parameter -r|--range was
added. For example:
 rpc.py bdev_ocssd_create -c nvme0 -b nvme0n1 -r 0-4

will create a bdev on parallel units 0 through 4 (inclusive).  If the
parameter is ommited, the bdev will span across all available units.
