Steven Hawkins reopened TEIID-3295:
-----------------------------------


Reopening since there was an issue found with detecting when to apply distinct to the subquery and we can now apply dependent joins later in planning via TEIID-3325

> Since TEIID-2149 the scope of the property has been limited in scope and should be flipped to true to allow for more efficient planning.  In the worst case users can use the NO_UNNEST hint to prevent the optimization.
