SPARK-12639 SQL Improve Explain for Datasources with Handled Predicates
SPARK-11661 Makes all predicates pushed down to underlying Datasources
regardless of whether the source can handle them or not. This makes the
explain command slightly confusing as it will always list all filters
whether or not the underlying source can actually use them. Instead
now we should only list those filters which are expressly handled by the
underlying source.
All predicates are pushed down so there really isn't any value in listing
them.
