Steven Hawkins resolved TEIID-686.
----------------------------------

    Resolution: Done

Modified TransformationMetadata to be backed by a MetadataStore that can be backed by index information or connector supplied metadata.  Also TransformationMetadata now has the responsibilities of the ServerTransformationMetadataFacade - that performed caching based upon name matches and object graph materialization.  We now expect the MetadataStore to return Table and Procedure records fully materialized, since their server usage pattern will always ask for the associated information soon after fetching the TableRecord anyway.  See TestVDBLessExecution.
