test/bdevio: add function to create target from single bdev 



Adding ability to create targets from single bdev,
will allow to create set of targets (not all) to run tests.

Idea is for bdevio to no longer run tests on all bdevs and
shutdown right after. Rather await RPC for configuring bdevs
then start test suite on select targets via RPC.
This is first patch in that direction.
