FLOW:
init=>start: Follower无法接收到Leader发出的
Heartbeat(即Election Timeout)
be_candidate=>operation: Follower变成Candidate
时间序列Term++
vote=>operation: Candidate
让剩下的nodes
进行Vote
reply=>operation: 其他的nodes进行vote
become_leader=>condition: Candidate
获取到大多数
nodes的投票
become_leader_yes=>operation: Candidate变成Leader
send_heartbeat=>end: 发送Heartbeat信息
停止其他节点的election
init->be_candidate->vote->reply->become_leader
become_leader(yes)->become_leader_yes->send_heartbeat
become_leader(no)->be_candidate
