- [ ] 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...

当参与者使用tcc注解@TwoPhaseBusinessAction时，同时添加@GlobalTransactional，比如在使用嵌套事务的场景下，目前2.x从1.x改造完tcc去spring后，无法同时添加两个注解切面。 1. 本pr修复了该问题，修复方案为遍历所有的InterfaceParser全部做解析，解析完成拿到ProxyInvocationHandler后，根据指定排序组织成一个代理链，执行调用时，按序进入多个切面。 2. 修复后支持添加多种类型的注解，比如@GlobalTransactional和@TwoPhaseBusinessAction为两类，可以同时添加。@TwoPhaseBusinessAction和saga注解化@CompensationBusinessAction是同一类，只允许添加一种，重复添加时启动阶段报错。 3. 切面进入顺序，@TwoPhaseBusinessAction优先@GlobalTransactional。

- [ ] I have registered the PR [changes](../changes). ### Ⅰ. Describe what this PR did 集成rocketmq到seata。 #### 关于总体解决思路： 本次集成的能力重点在全局事务的一阶段，我们会提供一个SeataMQProducer，在里面将以下两个方法自动加入到全局事务中。其他方法会调用到原生父类进行，不会加入到全局事务。 #### 关于具体实现方案及时序： 程序流程： 1. rocketmq按发送半消息（和rocketmq原有逻辑一样） 2. 执行本地事务executeLocalTransaction/executeLocalTransactionBranch（和rocketmq原有逻辑一样） 3. 如果state=成功，强行改回unknown，等待seata-TC调用rm决定二阶段。否则都将直接rollback这个消息（因为seata目前无法支持rm一阶段回查能力） ####...
