> Currently, it is possible for a leader at {{term x}} to send
> {{StartLeaderElection}} twice to a follower, making the follower become
> {{term x + 2}}.
> We can make StartLeaderElection idempotent by including a {{term}} in
> {{StartLeaderElectionRequest}}. And the receiver should ignore the
> {{StartLeaderElectionRequest}} from lower term.
> (Actually every request proto should include a senders term)
