From: Tomas Sedovic <[email protected]>
Adding a new cloud account imports all the backend realms from the given
provider. Additionaly, we add frontend realms that map to the backend.
Only one frontend realm is created for every actual realm that the cloud
provider serves, but each cloud account imports its own set of backend realms.
