Removed:
- dokuwiki (this was never properly set up)
- libvirt (this is already a virtual machine, double virtualization bad)
- openldap (this will become the responsibility of keycloak)
- openvpn (this will become the responsibility of head/tailscale)
- samba (this is now the responsibility of TrueNAS)
- searx (I never used this)
- gitlab (this has become the responsibility of gitea and hydra)
- syncthing (this was never properly set up)
The nix cache nginx entry is also paused, as it wasn't functional.
In this commit and the previous commit, the nginx config for the
minecraft server was also taken down, as the whole host is deleted.
The plan is to set it up again, this time using tsuki.
- Move `services/grafana.nix` to `services/grafana/default.nix`
- Split up all data collectors into separate files under
`services/grafana`
- Make grafana use postgres as its database
- Home config is now imported as a module from the host config
- The configuration takes variables to decide which settings to activate
- Extra fonts were added
- Some packages were added/reactivated
