drbd: Delayed creation of current-UUID
When a fencing policy of "resource-and-stonith" is configured,
and DRBD looses connection to it's peer, we can delay the
creation of a new current-UUID until IO gets thawed.
That allows one to deploy fence-peer handlers that actually
commit suicide on the machine they get started.
