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.
