Replica cannot be synced

[Git-Yang]

Problem Description:

• Node replicas cannot continue syncing when the batch message sync write process partially fails.

Cause Analysis:

1. The write of the batch replica fails partly. For example, the replica index is 1-4, index=1-3 is successfully written, but index=4 fails.
   
2. The master node sync request timed out , and resync the replicas with index=1-4.
   
   3.The slave node rewrites the batch replicas, but at this time writeIndex=3, request.getFirstEntryIndex() = 1, the check throws an exception, but the exception is not handled, causing the master node to time out again. Repeat the above process.
