Title: Do not throw errors for supervisor when success

Sometimes when a new service is added to supervisord it'll automatically start the service and it'll occur before supervisord state detects it, causing a race condition that makes supervisor try to start it, resulting in an error of already running. This change ignores common errors for stop/start.
