Description

As a follow-up in discussion of DRILL-4279, we want to clean up the current explain plan output, especially the Scan operator part.

For instance,

Scan(groupscan=[ParquetGroupScan [selectionRoot=file:/data/yelp/t1, numFiles=2, columns=[ ... ], files= ...

could be changed to:

ParquetScan(selectionRoot=file:/data/yelp/t1, numFiles=2, columns=[ ... ], files= ...
