The customer would like to have the server entry removed from HBI whenever he unregister the rhel via customer portal

At this moment, when registering the rhel via customer portal, the same will be available in access.redhat.com (api query), and it will also be available in the hybrid cloud (console.redhat.com). However, when doing the "subscription-manager unregister", the entry from access.redhat.com (again, via api query), will get removed, but the entry on the hybrid cloud will still be around.
