[PATCH blktests v2 06/11] nvme/rc: add blkdev type environment variable

[Shin'ichiro Kawasaki]

From: Daniel Wagner <dwagner at suse.de>

Introduce nvmet_blkdev_type environment variable which allows to control
the target setup. This allows us to drop duplicate tests which just
differ how the target is setup.
