RulePushAggregates should consider cost in addition to key information
----------------------------------------------------------------------

                 Key: TEIID-1510
                 URL: https://issues.jboss.org/browse/TEIID-1510
             Project: Teiid
          Issue Type: Feature Request
          Components: Query Engine
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 7.4

RulePushAggregates currently only considers whether a key is in use in the grouping columns to not stage an aggregate.  It should additionally use a cost check to see if the staged aggregate is cost effective.
