Apparently, this feature is being removed from all active ceph versions
and will not be present in future versions. Since we won't be able to
test it any more, and the api is provisional still, we just remove it
entirely.

The SubVolumeGroupPath function maps the subvolumegroup to a path from
the root of the cephfs, and works like `ceph fs subvolumegroup getpath
...`.
