In its current state, we can easily see which TPC-DS queries are using CTEs and
how those look like.

> Add a new test case similar to TpcdsCpuCostPlannerTest for validating the

> guard against regressions as the CTE logic evolves and also demonstrate and
> document which TPC-DS queries can benefit from the suggestion logic at the
> moment.
