Oslo team is actively getting rid of the old style generator.py in openstack/common/config. So we should switch to the newer oslo-config-generator which is the way forward. For simplicity's sake, i used one single list_opts in opts.py. However we can split this up and add entrypoints in setup.cfg if we decide to do that instead. blueprint oslo-config-generator Change-Id: Ib7c72af7be47df08983708ac6da0ce103518b78c
