What changes were proposed in this pull request?
It would be useful to support listing the columns that are referenced by a filter. This can help simplify data source planning, because with this we would be able to implement unhandledFilters method in HadoopFsRelation.
This is based on @rxin's patch (#13901) and adds unit tests.
How was this patch tested?
Added a new suite FiltersSuite.
