- unify test cases
- remove broken VersionedAttributes override abstraction
This overriding had no effect. The versioned.Attributes were never
used as admission.Attributes.Better make the versioned objects
explicit than hiding them under a wrong abstraction.
- remove wrapping of scheme.Convert
- internalize conversion package
