@kvijai82 why do some of the resources in this ClusterRole specify the plural name (appsodyapplications, serviceBindingRequests) and some specify the singular name (serviceMonitor, database)? Does it matter?

[kvijai82]

@ianpartridge that's the change I am trying to test out with Terrance today and will be creating a PR for. It does matter.

[ianpartridge]

If it matters, do they have to be singular or plural? I would guess plural, because that's what we had for the existing resources (appsodyapplications, openlibertyapplications). If I'm correct, I guess that means I should update this PR to say grafanadashboards?

[ianpartridge]

I saw that the CR you sent @tnixa was plural, so I've updated this PR accordingly. Hope that's correct.

Also added Secret and ConfigMap as two core resources we expect users will want to include in their GitOps repo. Secret is definitely required in order to get OpenLiberty metrics working (because the /metrics endpoint requires authentication).
