Test flow is to run fsstress after triggering quota rescan.
the ruler is simple, we just remove all files and directories,
sync filesystem and see if qgroup's ref and excl are nodesize.

v2->v3: addressed comments from josef:
- remove unnecessary redirections
- don't use _run_btrfs_util_prog() when capturing qgroup show output.
- turn off inode_cache mount option explicitly.
v1->v2: switch to _run_btrfs_util_prog()
