[ISSUE #1483] fix bug in QueryMsgByIdSubCommand print OffsetID twice

fix(broker):fix the issue that master node route info is lost when some node join the group in dledger mode

Since brokerId defaults to 0, it will register with nameserver before brokerId is changed when broker restart, causing the route info of master to be overwritten.
Set brokerId defaults to -1 in dledger mode and do not register wtih nameserver until brokerId is changed.
