Description:

"replication.election" is a child of "replication" (like "replication.rollback", for instance)

Engineering Ticket Description:

To aide diagnosing test failures, we should add logging any time we take an election-related action (election timeout expiring, calling for an election, voting in an election, etc), with all possible inputs to that decision (dump of heartbeat and spanning tree liveness tables, etc.).

This could be done with a new log sub-component, so that we can have higher verbosity in our tests than in prod.
