We have no tests for testing qgroups, so we have no way of knowing if our
changes are breaking qgroups at all. Get the ball rolling with some basic
functionality tests, these just make sure we can enable quotas and do rescan and
get sane values back, as well as make sure the limiting stuff works properly.
Thanks,
