Add Dashboards for k8s monitoring from a DB CR perspective

Hello,

For good monitoring experience, it will be good to provide dashboards for users from a DB point of view.
User Story would look something like this on k8s:
1. As a user I want to know what is the status of DB cluster
2. As a user I want to know the status of components associated with DB cluster, for example: Metrics of StatefulSet , Pods etc
3. I need option to specifically filter out on DB type or name etc.

I have created some dashboards, but custom resource metrics might also need to be captured https://github.com/kubernetes/kube-state-metrics/blob/main/docs/customresourcestate-metrics.md
