As a user, I want to have a pre-generated FQDN to get going fast

Implementation Notes

Some services require an FQDN to be configured. This can either be a custom one which the user controls themselv, or a system provided.

Every control-plane has a wildcard DNS configuration already, e.g. *.apps.exoscale-ch-gva-2-prod2.services.servala.com. Allow configuring this wildcard DNS per control-plane, in the form apps.exoscale-ch-gva-2-prod2.services.servala.com (without the star and dot).

Use this information to generate an FQDN for services that have a field spec.parameters.service.fqdn and put the generated value into the service configuration field. The user can still change that, but it makes it a lot easier to get started fast.

Generate the name this way: $instancename-$organization_namespace.$control_plane_wildcard.
Example: myforgejo-org-42.apps.exoscale-ch-gva-2-prod2.services.servala.com

This has to happen dynamically on the frontend, because the user can type any name in the Name field.
