IMPALA-5602: Fix kudu queries being incorrectly optimized as small query

Fixes a bug where queries on kudu tables that have all their predicates
pushed to kudu and have a limit were incorrectly being optimized as a
'small query' and therefore running on a single node with a single
scanner thread.

Testing:
Added planner test to verify small query optimization is not used
