repmgrd: catch cases where more than one node has initiated voting
...
The node(s) with higher ID will "yield", leaving the decision making
up to the node with the lower ID.
This happens very rarely, usually when the random delay is close
enough on two or mode nodes that vote initiation is simultaneous.

repmgrd: additional check to ensure only one node handles failover
...
It's possible the "failover" is completed by one repmgrd before the
other has a chance to react, in which case the am_bdr_failover_handler()
check will not apply. Instead check if the node record has already been
set to "inactive".

repmgrd: in BDR mode, have each repmgrd monitor each node
...
This will cover both the case when an entire node including
repmgrd goes down, and when one PostgreSQL instance goes down
but repmgrd is still up (in which case only one of the repmgrds
will handle the failover).

repmgrd: restrict BDR monitoring to two node setup
...
It's not safe to have more than two nodes with this kind of
"failover", so we don't need to select alternative nodes by
priority.

When registering a BDR node, sync repmgr.nodes from another node
...
If a BDR node is added via bdr_group_join(), repmgr.nodes will
start off empty, so we'll need to sync it ourselves before adding
it to the repmgr replication set.
