    ZOOKEEPER-3167:add an API to get total count of recursive sub nodes of one node

    1. In production environment, there will be always a situation that there are a lot of
recursive sub nodes of one node. We need to count total number of it.
    
    2. Now, we can only use API getChildren which returns the List<String> of first
level of sub nodes. We need to iterate every sub node to get recursive sub nodes. It will
cost a lot of time.
    
    3. In zookeeper server side, it uses Hasp<String, DataNode> to store node. The key
of the map represents the path of the node. We can iterate the map get total number of all
levels of sub nodes of one node.
