Description of problem:

In the global hub scenario, it allows to import an existing ACM cluster as a managed hub cluster. so the ACM addons are installed in the existing ACM cluster. when the user detaches this managed hub cluster, all the addons can be deleted. the policy crds can be deleted. But we do not want to delete the policy crds, because as a standalone ACM, the policy crds are required.
