[SPARK-10978][SQL] Allow data sources to eliminate filters
This PR adds a new method `unhandledFilters` to `BaseRelation`. Data sources which implement this method properly may avoid the overhead of defensive filtering done by Spark SQL.
Author: Cheng Lian <lian@databricks.com>
Closes #9399 from liancheng/spark-10978.unhandled-filters.
