From c1f79cd311ad62d3adb374921b8c3d303db5add6 Mon Sep 17 00:00:00 2001 From: Jim Hahn Date: Sat, 22 Feb 2020 17:11:20 -0500 Subject: 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).
