Naming modules failed to work properly during the nacos capacity expansion

[chuntaojun]

Describe the bug

A running Nacos cluster, if you want to expand a node at this time, you will find that the raft protocol of the naming module of the original cluster cannot recognize the newly added node, resulting in the naming module not working properly

Expected behavior

1. The node should be able to join the cluster normally
2. The old cluster can identify the newly added node, and the new cluster can work normally

Acutally behavior

see this issue ： nacos-group/nacos-k8s#166

How to Reproduce
Steps to reproduce the behavior:
1、Run a nacos cluster
2、modify old nacos cluster every member's cluster.conf file in {nacos.home}/conf
3、start a new nacos node that it's cluster.conf have old nacos cluster member info
4、see naming-raft or nacos.log will find err message like "can not find peer xxxx"
