glusterd: atomic store update.
All 'updates' to store are done in their respective tmp files and a rename to
their original copies is done in one pass. Failure to write or rename
successfully, promptly reduces the store's revision no., giving us an
opportunity to 'correct' it via peer 'detach-attach' operations, if need
be.
