> When a client reestablish to a server, it will send the watches which have
> not been triggered. But the code in DataTree does not handle it correctly.
> It is obvious, we just do not notice it :)
> scenario:
> 1) Client a set a data watch on /d, then disconnect, client b delete /d and
> create it again. When client a reestablish to zk, it will receive a
> NodeCreated rather than a NodeDataChanged.
> 2) Client a set a exists watch on /e(not exist), then disconnect, client b
> create /e. When client a reestablish to zk, it will receive a NodeDataChanged
> rather than a NodeCreated.
