Add frankfurt rules for Actor redesign
Note: VcpeTest and VfwTest are not included, as they depend on updates to the APPC and APPC-LCM Actors. Added feature-controlloop-frankfurt. Added HTTP client property files to feature-controlloop-management. Updates per review comments: - pom changes - simplify FrankfurtBase - rename event-svc-http.properties - change "usescases" to "frankfurt" - use blanks for CDS property defaults - trailing spaces in http-client files - add https property to http-client files Added newlines to config files that appear to be missing them (based on feedback from gerrit). Issue-ID: POLICY-2385 Signed-off-by: Jim Hahn <jrh3@att.com> Change-Id: Ib4a4d75461c734ae47309e41dc9d099e8815d55d
