【服务注册不正常】redis 开启哨兵模式（1主2从），tx-manager采用双节点

I have searched the [issues](https://github.com/codingapi/tx-lcn/issues) of this repository and believe that this is not a duplicate.

### 1. Bug Description
redis 开启哨兵模式（1主2从），tx-manager采用双节点，长时间运行后，当有新的服务启动时报错，不能注册到tx-maner上，重启tx-manger后可正常，但分别将tx-manger的双节点启动后，前端提示有3个tx-manger节点,

### 2. Environment:
- JDK version:1.8
- OS:win 10
- TX-LCN version:5.0.2
- Others: redis 5

### 3. Exception Stacktrace
重启tx-manager前的错误日志

将两个tx-manager分别重启后（每次都至少有一个在运行），可以看到最后一行的日志（TM cluster's size: 3）

### 4. Tour Idea
可能是redis集群导致，以前使用单节点时没有出现过类似情况，另外，已注册的服务，在重启时，有时候在tx-manager里面会显示两条信息

Tái hiện thiết lập với chế độ sentinel của Redis và hai node tx-manager, sau đó kiểm tra TMSearcher.java:80, AutoTMClusterEngine.java:83 và TCSideRpcInitCallBack.java:95. Bắt đầu từ exception count < 0 và các kích thước cluster được báo cáo; hoàn tất khi một service mới đăng ký thành công và frontend báo cáo số lượng node tx-manager thực tế mà không có exception.
