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).
