Provide configurable limits to the PointLookupOptimizer
Description
The PointLookupOptimizer can turn off some of the optimizations due to its use of tuple IN() clauses.
Limit the application of the optimizer for very low nDV cases and extract the sub-clause as a pre-condition during runtime, to trigger the simple column predicate index lookups.
