IMPALA-3586: Implement Union Passthrough

The union node acts as pass through operator and forwards row batches
from it's children without materializing. This is done in the case
when the child's tuple layout is identical to union node tuple layout
and no functions need to be applied to the child row batches.

Testing:
Verified that existing tests cover the case where no/some/all union
children of the union node can be passed through.
