Good point.  I thought about skipping TestRepairQuorum to avoid all
those if statements (which are also easy to forget when adding a new
test case) but it would be more hassle than just having the if
statements.

I now think the original approach was right, just simplify
has_quorum() using qemu_img_pipe() instead of using subprocess.
