As suggested by sterni, this makes the self-redirect of a machine to
its configuration a generic module working by convention.
In the process of moving this two small fixes have been applied:
* redirect is only applied if the URI is `/`, this is required for
ACME to work
* addSSL = true is added, otherwise we have a certificate but no TLS
listener
