<!-- Please make sure you have read and understood the contributing guidelines --> - [ ] I have registered the PR [changes](../changes). ### Ⅰ. Describe what this PR did 增加集群间元数据同步能力 1.leader选举成功后，生成只包含它自身的元数据，该元数据为一个单例，并同步至follower 2.follower收到这个元数据后，发送自身的元数据至server侧，进行补充follower的元数据 3.leader收到后，在元数据的follower中增加该节点，并推送元数据变更至client和其它tc节点 并且元数据中增加version字段，用于后续比如存在新旧多版本server，leader可以在同步的时候使用所有节点都能支持的协议，以便向下兼容。 Increase the ability of inter-cluster metadata synchronization 1. After the leader election is successful, generate metadata containing only itself, which is a singleton and synchronized to followers 2. After the follower receives this metadata, it sends its own metadata to the server side to supplement the follower's metadata. 3. After the leader receives it, add the node to the follower of the metadata, and push the metadata changes to the client and other tc nodes And the version field is added to the metadata for subsequent use. For example, if there are old and new multi-version servers, the leader can use a protocol that all nodes can support during synchronization for backward compatibility. ### Ⅱ. Does this pull request fix one issue? <!-- If that, add "fixes #xxx" below in the next line, for example, fixes #97. -->  ### Ⅲ. Why don't you add test cases (unit test/integration test)? ### Ⅳ.
