feat(wpcarro/terraform): Encode diogenes as terraform configuration r/3485

Some reference commands for my future self (blog post forthcoming?):

```shell
$ nix-shell -p google-cloud-sdk terraform
$ gcloud auth application-default login # stateful
$ terraform init
$ terraform apply
```

What's left for feature parity?
- Encode 100GB external disk as resource
- Encode firewall as resource
- Ensure marcus can SSH to instance

Stretch goals:
- Spin-up fully NixOS-configured instances
