feat(ops/terraform): add module for deploying NixOS system closures r/5867

This module makes it fairly easy to deploy NixOS system closures using
Terraform, while properly separating the evaluation of a
derivation (to determine whether a deploy is needed) from the building
and copying of the closure itself.

This has been on my stack for a while. It was originally developed for
Resoptima, who agreed to open-sourcing it in depot back when we
completed our work with them. Their contribution has been acknowledged
in the README.
