Descripción

**Describe the bug**
use RatisConsensus.addPeer to migrate data/schema region, but it does not works

**To Reproduce**
Steps to reproduce the behavior:
1. insert data to device
`SET STORAGE GROUP TO root.ln;
CREATE TIMESERIES root.ln.wf01.wt01.status WITH DATATYPE=BOOLEAN, ENCODING=PLAIN;
CREATE TIMESERIES root.ln.wf01.wt01.temperature WITH DATATYPE=FLOAT, ENCODING=RLE;
INSERT INTO root.ln.wf01.wt01(timestamp,status) values(100,true);
INSERT INTO root.ln.wf01.wt01(timestamp,status,temperature) values(200,false,20.71);`
2. the data region **RG1** is on **Node1** and **Node2**.
3. call RatisConsensus.addPeer at **Node1** to add a new peer(**Node3**) for **RG1**.
4. it not woks, and repeat a same log info in **Node1**:

5. repeat log info in new peer Node(**Node3**) :

Línea de trabajo

Comienza reproduciendo la migración de RG1 con el SQL proporcionado y la llamada a RatisConsensus.addPeer; después, inspecciona los logs repetidos de setConfiguration y APPEND_ENTRIES de Node1 y Node3. Se considera completado cuando Node3 se une correctamente a RG1 y la región de datos y esquema migrada puede utilizarse allí.
