refactor: use options for config parts

This works towards having reusable modules * `config.pub-solar-os.networking.domain` is used for the main domain * `config.pub-solar-os.privacyPolicUrl` links towards the privacy policy * `config.pub-solar-os.imprintUrl` links towards the imprint * `config.pub-solar-os.auth.enable` enables the keycloak installation. This is needed because `config.pub-solar-os.auth` has to be available everywhere, but we do not want to install keycloak everywhere. * `config.pub-solar-os.auth.realm` sets the keycloak realm name
