As I understand from DRILL-1921, cross join was prevented due to the
`CannotPlanException` exception at the planning stage.
Can we get the same problem using `APPLY`? If yes, should be discussed the
possibility of adding some limitations for `APPLY`, for example, deny usage for
the case when a filter is absent in the query etc.---
