Review comment:
   why add an abstract class that has only one child?

Review comment:
   It's a bit weird that `TPCDSBase` and `TPCHBase` are not at the same 
level (`TPCDSBase` is much more complicated). Can we do a bit more refactoring? 
Probably pull out some logic (e.g. `createTable`) from `TPCDSBase` to 
`PlanStabilitySuite` or a new `trait`.

Review comment:
   nit: we should not remove the `protected` modifier here. It forces all 
the traits/classes extending this trait to also remove the `protected` 
modifier, which is an unnecessary breaking.
