We occasionally see the ECS APIs called by ecs_exporter 500 on the first request or two, so the metrics served by the exporter are nonsense. By using NewInvalidMetric in response to Collect, we can ensure that HTTP 500s are served on /metrics whenever such errors occur. Closes prometheus-community#97.
