Subject: [RFC v1 1/1] nvme: Limit runtime for verification and limit test image size
The reduce the overall runtime of the testsuite by limiting the runtime
of the verification jobs. We are only interested that some normal I/O is
transferred between host and controller.
Also limit the resource usage of the tests. This allows to run more tiny
VMs and thus more parallel blktests on the same machine.
