URL: https://github.com/apache/arrow-datafusion/issues/2180

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   in `datafusion.proto`
   ```
   message AggregateExprNode {
     AggregateFunction aggr_function = 1;
     repeated LogicalExprNode expr = 2;
   }
   ```
   
   in `ballista.proto`
   ```
   message PhysicalAggregateExprNode {
     datafusion.AggregateFunction aggr_function = 1;
     PhysicalExprNode expr = 2;
   }
   ```
   it will make below query fail in serilize at executor. beacust `approx_percentile_cont` AggregateExp has two args.
   ```
   select approx_percentile_cont("o_totalprice", 0.5) from orders;
   ```
   
   **Describe the solution you'd like**
   Make 
   ```
    repeated PhysicalExprNode expr = 2;
   ```
   **Describe alternatives you've considered**
