Steven Hawkins resolved TEIID-4788.
-----------------------------------
    Resolution: Done


Changed the logic to not create temporary Database or VDBMetadata representations - only 1 will be created as necessary.  There is still a small performance issue in creating temporary MetadataFactory instances.

> For many ddl operations, a fresh transformationmetadata instance is created, which requires converting the Database to runtime form.  The larger the DDL vdb, the more expensive this becomes.
