https://github.com/apache/zookeeper/pull/639
a problem is when the network get disconnect, the client will enter into
two state, one is ZOO_EXPIRED_SESSION_STATE, the other is ZOO_CONNECTING_STATE,
the problem is the client didn't reconnect to server when enter into
ZOO_CONNECTING_STATE. I'll have a check on this---
