Kaijie Chen updated RATIS-1818:
-------------------------------
Description:
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)
