list of potential improvements for internal/controller/operator/factory/finalize package:

• remove finalizers from core resources, as they don't provide any value, leads to dangling resources during cleanup or removal and rjust equire extra patch request to remove finalizers
• replace ownerreferences for cluster wide resources with selectors. cluster wide resources can only have a cluster wide resources as an owner, in our case we're using CRD as owner reference, which makes no sense. replace it with label selector.
• some namespaced resources use selectors instead of owner reference to define which objects should be removed, replace this logic with ownerreferences check
