Discuss if we should use OwnerReferences instead of component references to get artifacts

[frewilhelm]

Description

In https://github.com/open-component-model/ocm-k8s-toolkit/pull/30 the component artifact is retrieved by using:

err := r.Get(ctx, types.NamespacedName{
		Namespace: resource.GetNamespace(),
		Name:      component.Status.ArtifactRef.Name,
}

Instead of using this explicit reference to the component, we could consider using k8s OwnerReference of the component to get the respective artifact.
