test/nvmf: zero-copy test 



The test has two phases: first it runs a bdevperf with rw=verify to
check data consistency and then runs bdevperf in the background while
sending RPC requests causing the subsystem to be constanty
paused/resumed.

In-capsule data is set to 0 to make sure all IO requests are using
zero-copy.
