Bug 570486: [Architecture] Update CDO implementation of the Architecture Model

- update source Ecore and generator models to match core models
- regenerate CDO implementations from latest model and codegen templates
- add missing implementations of new interface methods
- fix missing implementations of methods that had been generated
  previously as TODOs throwing UnsupportedOperationException
- delete obsolete UML models as in the core
