glusterd: Fail volume 'modify' operations when rb is ongoing
* add-brick, stop-volume, remove-brick are the operations that are explicitly 'failed' when attempted while replace-brick is in progress. * we attach the volume-id to the dst_brick volfile ensuring that the replace-brick operation holds 'claim' on it.
