Description

After HBASE-20148, serial replication will be an option for peer. Since an instance of ReplicationSourceWALReader can only belongs to one peer, we do not need to add the so many 'if' in the implementation of readWALEntries to check whether we should consider serial replication. We can just make a sub class or something similiar for serial replication to make the code clean.
