Onder Kalaci ae3fd6e10d Disallow subqueries without a relation in the range table list for INSERT .. SELECT 
This commit disallows subqueries without relation in the range table
list. This commit is only applied for INSERT.. SELECT queries.

The reasoning behind this limitation is that if we allow pushing down
such queries, the result would include (shardCount * expectedResults)
where in a non distributed world the result would be (expectedResult)
only.
