Remove usecases and legacy actor code

Made the following changes to remove usescase and legacy actor
code:
- deleted the usecases controller and feature
- deleted code associated with legacy actors, with the exception
  of AaiManager, which is needed by RestControlLoopManager
- moved the contents of the "guard" project into the m2/guard project,
  as that is the only thing that still needs it
  - modified the m2/GuardContext to get the name of its persistence unit
    from the properties so it could be overridden by junit tests
  - used eclipselink constants

Also fixed a bug in the properties for the VFC actor.

Addressed review comment:
- removed usecases from Dockerfile
