+================================
+Role - edpm_tripleo_cleanup
+================================
+
+Role stops and disables all systemd units enumerated to it.
+If the role doesn't recieve list of services, it will instead stop and disable
+all units containing string "tripleo" in their name.
+
+This way we can effectivelly prevent any leftovers of original tripleo based
+deployment from interfering with post-adoption setup.
