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 Issue-ID: POLICY-2558 Change-Id: I677d68c9efed9247c3d55773abdcc736b577a6b4 Signed-off-by: Jim Hahn <jrh3@att.com>
