Hi, I took care of implementation of [1] in Neutron and I have couple questions to about this goal. 1. Should we only change "restart_method" to mutate as is described in [2] ? I did already something like that in [3] - is it what is expected? 2. How I can check if this change is fine and config option are mutable exactly? For now when I change any config option for any of neutron agents and send SIGHUP to it it is in fact "restarted" and config is reloaded even with this old restart method. 3. Should we add any automatic tests for such change also? Any examples of such tests in other projects maybe?
