We need to take a read lock when reading any of the FSM fields. Expose a
new fsm.Stats to handle a racy read and make sure we're consistently using
the f.db read lock wrappers.
Add some metrics helpful for monitoring raft cluster state.
Furthermore, we weren't emitting bolt metrics on regular (non-perf) standbys, and there were other metrics
in metricsLoop that would make sense to include in OSS but weren't. We now have an active-node-only func,
emitMetricsActiveNode. This runs metricsLoop on the active node. Standbys and perf-standbys run metricsLoop
from a goroutine managed by the runStandby rungroup.
