This commit adds a shutdown logger which will send a request for shutdown on critical errors. It uses the signal package to request safe shutdown of the daemon. Since we init our logs in config validation, we add a started channel to the signal package to prevent the case where we have a critical log after the ShutdownLogger has started but before the daemon has started listening for intercepts. In this case, we just ignore the shutdown request.
