WIP: consensus: disarm failure detector around elections
This is a more complete fix for KUDU-2149 which disarms the failure detector
completely around a leader election.
There are several changes to make this happen:
1. The FD is changed to use a one-shot timer, which automatically disarms
upon firing.
2. Because all elections are guaranteed to reach DoElectionCallback, that's
where we rearm the FD.
3. We provide a special case for pre-elections where FD rearming is deferred
until after the subsequent real election finishes.
WIP because it's still pretty brittle; maybe there's a more robust approach?
