   跟踪调试代码发现即使dubbo创建一个CuratorZookeeperClient，但是发现有的UT会建两个session，最后只关了其中一个，导致zk服务关闭后另一个没有关闭的session不停地尝试重连，查了半天，才发现是ZookeeperServiceDiscovery自己另起炉灶搞了一套连接，但是destroy的时候并没有关闭。
   本来想把ZookeeperServiceDiscovery的zk连接改为ZookeeperTransporter统一搞，但是动手时发现ZookeeperServiceDiscovery自己不仅有自己一套的连接参数，还有自己的一套状态管理，改动起来伤筋动骨，还是等熟悉ZookeeperServiceDiscovery的commiter重构算了，我先给它的destroy方法补个zk连接关闭操作算了。
