If we do want to move to a common infrastructure, then IMHO this patch
series should do the work to convert qemu-iotests to use it.

Currently this is simply introducing a 2nd way to write block tests.

We know from bitter experiance that when we introduce a new system in
QEMU without converting the old system, the old system will live forever
increasing our maint burden & creatnig confusion for developers about
which is the preferred approach.
