Description
When monitors are joining a cluster, they may send an MMonJoin message to place themselves correctly in the map in either handle_probe_probe() or finish_election(). These messages must be sent to the leader — monitors do not forward each other's messages.
Unfortunately, in these instances they rely on the old behavior that the numerically-first monitor in the quorum will be the leader, by directing it to *quorum.begin(). Fix it so they have the proper leader (it must be transmitted in MMonProbe) and use it.
