Is your feature request related to a problem or challenge? Please describe what you are trying to do.

As apache/datafusion#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.
