bfda995be2 bdev/compress: add RPC to specify PMD
By default QAT will be selected if available however a new RPC
can be used to either auto-select (default) or specify either
ISAL or QAT.

600341b6c5 bdev/compress: replace RPC parm name with pm_path
We decided to name compress bdevs with COMP_ and then the name of
the underlying bdev so the RPC parm name was stale.  Previously
hardcoded the path to PM for early dev so replaced name with pm_path.

Note that a sample create looks like this now:

rpc.py construct_compress_bdev -b NVMe0n1 -p ~/pm_files -d compress_isal

And that devs need to pay attention for the pathname they provide, its
easy to leave orphaned pm files around and they can get big.
