This builds on I644608b4e197ddea31c5f264adb492f2c8931f04 and
adds a revert resize test which deletes the source compute service
while the server is in VERIFY_RESIZE status and then reverts the
resize. The results are a bit different from the confirm scenario
because the confirm fails while the revert actually works which
is more dumb luck based on where the compute service drops the
move claim during the revert process (on the dest which still exists
rather than the source).
