For FedRAMP, we are trying to use managed DNS (https://github.com/openshift/hive/blob/master/docs/using-hive.md#managed-dns-1)

However, we found that the ClusterDeployment controller creates a DnsZone CR with a region that can only be us-east-1 or cn-northwest-1 (https://github.com/openshift/hive/blob/1575b9557e00ac39f13eaf3c15c1acd6bec6d756/pkg/controller/clusterdeployment/clusterdeployment_controller.go#L1554-L1581). After manually changing the generated DnsZone CR with a region of us-gov-west-1, we get the following error in the Hive controller logs:

InvalidInput: Operations related to PublicDNS are not supported in this aws partition. 

Does managed DNS support private zones/AWS GovCloud?
