[TC] Test quota limits are honored on rebalance + heal
Test case: * Enable quota on the volume. * Set hard and soft time out to zero. * Create some files and directories from mount point so that the limits are reached. * Perform add-brick operation on the volume. * Start rebalance on the volume. * While rebalance is running, kill one of the bricks of the volume and start after a while. * While rebalance + self heal is in progress, create some more files and directories from the mount point until limit is hit.
