Proposed title of this feature request

What is the nature and description of the request?

We are introducing the Incident detection feature in the ACM as well. This means that the multicluster-observability-addon (MCOA) depends on the cluster-observability-operator (COO) and it would be better to depend only on the COO APIs and not the full operator. This is currently not possible and it's the main goal of this feature.

Why does the customer need this? (List the business requirements)

I think it's not really customer facing, but the decoupling is improvement for the future.

List any affected packages or components.

COO codebase. Additionally the API should not depend on the controller-runtime.
