fix: skip ghost alerts

        Alert alert = alerts.get(0);

        String container = alert.getLabels().get("container");

        if (container == null || container.isEmpty()) {

            logger.warnf("Alert did not belong to hypo service");

            return Response.ok().build();

        }

        logger.infof("Received a new alarm from Grafana Loki for %s", container);

        logger.debugf("Received: %s", grafanaPayload.toJsonString());
