Description
In #1364 there was some discussion about the current value of ElectionTicks (3 seconds) being too low. This can trigger unnecessary leader elections. We should consider increasing ElectionTicks to something more like 9 seconds. This would mean that the swarm could be unavailable for slightly longer before performing a leader election to recover, but spurious leader elections would happen less often.
Also, ElectionTicks should be configurable. This is tracked in #1326.

Research direction
Start by locating the ElectionTicks definition and reading the discussion in #1364. Review #1326 to understand the separate configurability work, then determine how an increased default would affect leader-election recovery and spurious elections. Done means the intended default and configuration scope are settled and validated against the issue’s tradeoff.
