I finally got the application monitoring stack working, and reading a ServiceMonitor for the operator so that metrics show up in prometheus. I think it might actually be possible to just have one ServiceMonitor in the application-monitoring namespace that would cover all the operators in all namespaces that have the monitoring_key=middleware label, but I'm not sure if that's a good idea, or if it would be better to have one per operator.

I also don't know what would be useful yet to show on a dashboard for an operator. I asked some of the integreatly people, and they don't appear to have anything for the operators in this regard.
