WIP: add installer generation and deployment scripts
This doesn't work yet for reasons that are not entirely clear to me:
> nix run .#deploy.all --show-trace
error: 'nixosConfigurations.all.type' is not a string but
sic!
> nix build .#installers.all
warning: Git tree '/home/vg/src/simple-nixos-fediverse' is dirty
error:
