    @TyqITstudent  quick comment:
    - you can follow an example of `GetChildren2Test`,create an UT:e.g 
`GetAllChildrenNumberTest`，create some zk-nodes,then do some asserts of the 
number of the specific node. do a relevant test in the `DataTreeTest `could be 
better. 
    - BTW:
         the codes need another rebase.
         change the github tilte to "`ZOOKEEPER-3167:add an API to get total 
count of recursive sub nodes of one node`"
