Remove btrfs quota groups after containers destroyed
Remove btrfs quota groups after containers destroyed

This fix tries to address the issue raised in 29325 where
btrfs quota groups are not clean up even after containers
have been destroyed.

The reason for the issue is that btrfs quota groups have
to be explicitly destroyed. This fix fixes this issue.

This fix is tested manually in Ubuntu 16.04,
with steps specified in 29325.

This fix fixes 29325.
