Restructure planning
--------------------

                 Key: TEIID-902
                 URL: https://jira.jboss.org/jira/browse/TEIID-902
             Project: Teiid
          Issue Type: Task
          Components: Query Engine
    Affects Versions: 7.0
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 7.0


All transformation queries should be cached - not just views.
All cached queries should already be validated - and not revalidated with every request.
Cached queries should be stored individually - not as full and separate trees as they are now, where the same view command exists can exist multiple times in cache.

The choice about whether to use a materialized view or not should also be moved to planning time - not a resolver activity.

We should remove the concept of non-embedded command from everything except planning logic.  It's error-prone and confusing in a resolving/rewrite context.
