> Add support for generating optimized logical plan for simple query, 
> 1. project and filter: SELECT a, b + 1 FROM MyTable WHERE b > 2
> 2. values: SELECT * FROM (VALUES (1, 2, 3)) AS T(a, b, c)
> 3. union all: SELECT a, c FROM (SELECT a, c FROM MyTable1 UNION ALL SELECT a, c FROM MyTable2)
> {{Union}} depends on {{Aggregate}} to eliminate duplicates, so it will be introduced after {{Aggregate}} spported.
