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

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.

Store the replication user in repmgr.nodes
...
When creating recovery.conf outside of "repmgr standby clone",
there was no way of knowing if a replication user had been
explicitly provided with --replication-user, meaning the value
of "primary_conninfo" would be set to the "conninfo" field of the
node's upstream node record.
We'll add an extra column to store the replication user for each
node so it can be referenced at any time.
