fixed not to try to reconnect when session and connection timeout.

The application received the zookeeper event without any problems after network is reconnected.

e.g.
RetryPolicy retryPolicy = new ExponentialBackoffRetry(Config.BASE_SLEEP_TIME_MS, 3);
CuratorFrameworkFactory.newClient(connectString, 20000, 10000, retryPolicy);


But following example is not working after network is not available for about 30s.

e.g.
RetryPolicy retryPolicy = new ExponentialBackoffRetry(Config.BASE_SLEEP_TIME_MS, 3);
zkClient = CuratorFrameworkFactory.newClient(connectString, 10000, 10000, retryPolicy);

The application didn't receive any zookeeper event after this reset() method is invoked.
