In Octopus 15.2.2 there is an rbd change that causes the rbd ls command
to hang if there are not sufficient OSDs to meet the replica requirement.
The smoke suite just started hanging today since the 15.2.2 image was
released with this change. Therefore, the test that resizes the pool
to replica 3 must resize back to 1 before cleaning up.
