Change subject: IMPALA-4859: Push down IS NULL / IS NOT NULL to Kudu

I think we should also add an end-to-end. In particular, I'm curious what Kudu 
will do when we pass it an IS NOT NULL predicate on a primary-key column or 
another non-nullable column.

File 
testdata/workloads/functional-planner/queries/PlannerTest/kudu-selectivity.test:

Line 152:      predicates: CAST(date_string_col AS TINYINT) IS NULL
can move this into the query above, so we have one query with all the cases?
