+   2. 节点注册时加上自己是有状态还是无状态还是有序。每个服务注册时加上自己能接收的消息范围。(节点是否有状态参考service.proto来处理，无需注册到etcd。服务消息范围也没必要加上，类似于EnterRoom消息所有玩法都需要处理。还是交给客户端发消息时自行决定发到哪类节点)

+   3. gate根据消息id决定路由给哪类节点，根据节点是否状态服选择节点。（同上）
    4. 通过广播机制，将玩家在哪个状态服里同步给所有服，保存到内存里。(后续优化，暂不考虑)
+   5. 优化rpc及send通过serviceTypeId来处理向哪一个节点发送消息。(已优化，避免每次都要查找node)
