After  (ProjectionNode) was implemented, we need additional logical scans with Convention#NONE convention for optimizations requests with predicates.
1. Implements IgniteLogicalTableScan and IgniteLogicalIndexScan with inheritance from ProjectableFilterableTableScan
2. Move and change ValuesConverterRule form HEURISTIC_OPTIMIZATION into OPTIMIZATION
3. ExposeIndexRule refactoring.
4. New converter IgniteLogical[Table|Index]Scan -> Ignite[Table|Index]Scan
