   @viirya @parthchandra @mbutrovich This is still WIP but let me know what you 
think of the overall approach here if you have time.
   
   Current status is that we now log the metrics that we are dropping. Here are 
two examples from TPC-H q3. 
   
   We wrap an aggregate in a projection causing:
   
   ```
   Dropping the AggregateExec elapsed_compute time of 1820330 for plan 
ProjectionExec (#624)
   ```
   
   The input to a SortExec is a ScanExec to fetch the input batches from the 
JVM, and we drop those metrics:
   
   ```
   Dropping the ScanExec elapsed_compute time of 1151562087 for plan SortExec 
(#0)
   ```
