Steven Hawkins resolved TEIID-2149.
-----------------------------------

    Resolution: Done

Changed the default to apply to the rewriter, added a release note, and updated the docs.  Also added an Options class that should be used to rather than direct system property manipulation.

> subqueryUnnestDefault should only apply during rewrite, since it is run without cost analysis.
> However the unnest logic should always run in the optimizer and if necessary the user can use the NO_UNNEST hint to keep the subquery inline.
