feat(wpcarro/diogenes): Nixify diogenes's Terraform configuration

TL;DR:
- Define googleCloudVM function to provision NixOS VMs on Google Cloud.
- Consume googleCloudVM in diogenes/default.nix
- Define README.md for basic usage instructions (subject to change).
- Delete diogenes's HCL
- Remove `diogenesSystem` from meta.targets

I'm still having trouble with DNS:
- I need to transfer the Google Domains config to Cloud DNS
- `host billandhiscomputer.com` is NXDOMAIN, so I don't trust my tf DNS config
- This is preventing me from getting SSL certs, which blocks my website, quassel

# diogenes
diogenes is a NixOS machine deployed on a Google VM. It hosts
https://wpcarro.dev.
## Deployment
I manage diogenes's deployment with Terraform. My current workflow looks like
this (highly subject to change):
```shell
cd /tmp/terraform # or any directory that hosts terraform state
outpath=$(nix-build /depot -A users.wpcarro.nixos.diogenes)
cp <out-path> .
nix-shell -p terraform google-cloud-sdk # gcloud to authenticate if necessary
terraform init/apply
```
