feat(wpcarro/terraform): Support SSH r/3498
Supporting SSH turned-out to be a bit of a saga... Thank you @espes and @grfn
for the pointers.

Problem: When I originally setup my Google VM, I followed this tutorial,
https://nixos.wiki/wiki/Install_NixOS_on_GCE, so I ended-up installing
`nixos-20-03`: an older version of NixOS, (the newest version in `gsutils ls -l
gs://nixos-images`). Critically, I missed this important footnote:

> NOTE: Newer images (from 20.09 on) won't be available at the bucket above, and
> will instead need to be found at
> <nixpkgs/nixos/modules/virtualisation/gce-images.nix>.

It turns out that *newer* images include this script...
https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/virtualisation/fetch-instance-ssh-keys.bash
...which reads the key, "sshKeys", from the Google metadata server and copies
the value into /root/.ssh/authorized_keys.

To make matters a bit misleading, the NixOS script expects the key to be
"sshKeys", but Google deprecated that in favor of "ssh-keys" (hence why both
versions appear in this commit).

TL;DR:
- upgrading to a newer NixOS image
- adding an empty access_config block so Google will assign my VM an external IP
- removing oslogin (not necessary to do, and I may add it back later)
- adding my public SSH key as metadata
