Gian Merlino ac84a3e011 SQL: Add resolution parameter, fix filtering bug with APPROX_QUANTILE (#3868)
* SQL: Add resolution parameter to quantile agg, rename to APPROX_QUANTILE.

* Fix bug with re-use of filtered approximate histogram aggregators.

Also add APPROX_QUANTILE tests for filtering and running on complex columns.
Includes some slight refactoring to allow tests to make DruidTables that
include complex columns.

* Remove unused import
