   **Is your feature request related to a problem or challenge? Please describe 
what you are trying to do.**
   
   
   As https://github.com/apache/arrow-datafusion/issues/361 all feature has 
been done in datafusion. We can bring window function in ballista ✌️
   
   I have implement a simple version in my repo. But we need do some change in 
datafusion.

   **Describe the solution you'd like**
   
   After we use the related version datafusion, will implement some window 
function   `Physical plan`  encode and decode features.
   
   I have checked with datafusion,  If the window function  `PARTITION BY` and 
`ORDER BY`, the physical  planner of datafusion has helped to add `repation` 
and `sort`. So we no need to deal `window_func` in `plan_query_stages_internal`.
