A Grafana Dashboard Plugin to Observe Controller Metrics

This project aims to provide unified Grafana dashboards to visualize K8s controller/operator status based on Kubebuilder. In general, users have to design and create their own Grafana dashboards to observe their controllers/operators. It would be great if we can provide a unified and comprehensive one, then users may: 1. easily visualize controller/operator metrics 2. avoid duplicate creation across different teams 3. have more insights given by the rich content in the dashboard Basically, I plan to create a Kubebuilder plugin, that can be simply triggered to provide: 1. dashboard resource that users can easily apply 2. selective dashboards to bring more insight in certain fields Additionally, this project also covers following features collected from the community: 1. dashboard auto-installation when controllers are deployed 2. new metrics to instrument user-defined CR 3. additional dashboard to observe CR/CRD related resources Ideally, the project would provide a full-featured yet simple solution for users to monitor their CRs and relative controllers in detail.
