> Pre vote before request vote

> Issue Type: New Feature

> For example, leader is s1, and s2, s3 are the followers. If there is
> something wrong with s3's network, and s3 lose connection with leader in a
> short time interval, s3 will trigger election. when s3's network recovery,
> leader will step down which is unnecessary. So I want to add pre vote before
> real vote.
> 1. if s3 want to request vote, it first send a pre vote request.
> 2. when s1 and s2 receive pre vote request of s3, they check their
> electionTimeout to decide whether should trigger leader election.
> 3. If s1 and s2 refuse to trigger a new leader election, s3 still keep as
> follower.
