Murat Tuncer b36b59dd4f Relax reference table restrictions in subquery union pushdowns
We used to error out if there is a reference table
in the query participating a union. This has caused
pushdownable queries to be evaluated in coordinator.

Now we let reference tables inside union queries as long
as there is a distributed table in from clause.

Existing join checks (reference table on the outer part)
sufficient enought that we do not need check the join relation
of reference tables.
