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: 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.
