btrfs: add test for enable/disable quota and create/destroy qgroup repeatedly
Test enable/disable quota and create/destroy qgroup repeatedly in
parallel and confirm it does not cause kernel hang. It only happens
in kernel staring with kernel 5.17-rc3. This is a regression test
for the problem reported to linux-btrfs list [1].
The hang was recreated using the test case and fixed by kernel patch
titled
btrfs: qgroup: fix deadlock between rescan worker and remove qgroup
