一个Node stepped down 之后，集群无法响应客户端请求

4

目前情况是有5个节点，其中一个节点出现了如下日志： ``` I1125 03:38:29.105105 36781 /home/zyh/braft/example/atomic/server.cpp:305] Node stepped down : Raft node receives higher term request_vote_request. ``` 其他节点看起来正常，但客户端请求全部超时了。 另外，目前节点step down之后似乎是无法恢复的，是否应该让step down的节点，在收到新leader节点消息后重新变为follower呢？

出现大量 reject term_unmatched AppendEntries 错误

使用atomic_server测试，发现某一节点出现大量 `reject term_unmatched AppendEntries`错误，且客户端操作都超时了。 日志如下，其中节点1和2在测试开始后不久被`kill`掉，因此master一直报连不上两个节点。 [log_app_err0_0.txt](https://github.com/baidu/braft/files/7389277/log_app_err0_0.txt) [log_app_err1_0.txt](https://github.com/baidu/braft/files/7389280/log_app_err1_0.txt) [log_app_err2_0.txt](https://github.com/baidu/braft/files/7389281/log_app_err2_0.txt) [log_app_err3_0.txt](https://github.com/baidu/braft/files/7389282/log_app_err3_0.txt) [log_app_err4_0.txt](https://github.com/baidu/braft/files/7389284/log_app_err4_0.txt)
