Feature Request

Is your feature request related to a problem? Please describe. We are using a CI/CD tool to reconcile all resources that we installed into our k8s cluster with it. Due to a drift in the ClusterServiceVersion packageserver resource, the chart is getting updated all the time.

Describe the solution you'd like We'd like to be able to set annotations. Ideally setting annotations would be possible for all important resources.

I am trying to do something similar, I would like for any installed operators to be able to configure their respective resources with annotations. For instance, ensuring a resource has the right ServiceAccount roles serviceAccount.annotations.eks\\.amazonaws\\.com/role-arn" = "arn:aws:iam::<acct_id>:role/<role_name>"

Admittedly, I may just be uninformed if a solution to this already exists? But I'm still learning OLM.
