Consider moving Factory and related exception classes to org.opengis.util
Description
The Factory interface is currently defined in the org.opengis.referencing package, because the concept of factories in GeoAPI was initially inherited from the OGC 01-009 specification (which is about referencing). Since this factory interface and its exception came to be used by many kind of factories, it would make more sense to put them in the org.opengis.util package.
