The advantages of having a user for each adminstrator:
* Better security analysis: who issued executed what command, who
touched which file, who used sudo at which time.
* Possibility of granular access, e.g. person X is only allowed to
manage service Y
This commit removes the flora-6 host. All services are moved to
trinkgenossin, with the drone service being removed completely in favour

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
