IMPALA-5602: Fix query optimization for kudu and datasource tables
Fix a bug where the following queries on kudu and datasource tables
were incorrectly being optimized as a 'small query' and therefore
running on a single node with a single scanner thread:
(A) that have all their predicates pushed to the underlying storage
layer and have a limit
(B) table stats missing + Conditions in (A)
Testing:
Added frontend planner tests.
