 1. fetching EKS auth as config map? and pass to module (version, etc) as object?
 2. automatically pass config option as objects? (aws adot add-on: enable cert-manager, cert-manager version?)
 3. Test case for every option possible? 
+4. Need data source for AMP - https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/prometheus_workspace, Bryant's module doesn't seem to support splitting usage (eg. using multiple alerting rules ONLY)
