DRILL-6089 Removed ordering trait from HashJoin in planner
HashJoin typically does not preserve ordering in most databases. Drill's
HashJoin operator technically preserved ordering up to this point, but after
spilling is implemented it will no longer preserve ordering. This change makes
sure the planner knows that HashJoin does not preserve ordering.
All unit and functional tests are passing @amansinha100 @Ben-Zvi please
review.
