The current version is pretty useless:
- "rbd bench" writes the same byte (0xff) over and over again, so
almost all checksumming is in vain
- snapshots are taken in a steady state (i.e. not under I/O), so no
race conditions can get exposed
- even with these caveats, it's not wired up into the suite
Redo this workunit to be a reliable reproducer for the issue fixed
in the previous commit and wire it up for both krbd and rbd-nbd.

/bin/bash is a Linuxism. Other operating systems install bash to
different paths. Use /usr/bin/env in shebangs to find bash.

Stress test that does io on an image while we are mirroring a diff from
earlier snaps to a second copy. At the end, verify that all snaps have
matching content.
