test deployments using data obtained through the data model in VMs.
caveats:
- SSH currently has a `run` abstraction that the nixops4 model still lacks
- the deployed (trivial) configuration on activation has not facilitated new ssh connections (for subsequent) updates, i.e. a more sophisticated configuration would be needed for real-life usage.

Closes#103
At last, a fully fledged data model for what Fediversity really is and does. This comes with a test that exercises a very simple but functionally complete arrangement with all ingredients fo the business logic: a dummy resource (login shell), a dummy application (`hello`, which needs a shell to live in), a dummy environment (a single NixOS VM that allows for one, the operator's, login shell), and a deployment of that environment given a dummy configuration (that enables `hello`).
The next step will be to lift this purely evaluation-level test into a VM test which verifies that the resulting VM indeed has `hello` deployed to the operator's user account.
Caveats:
- The exact naming has a bit of room for improvement, and may have diverged from the design document
- The test is not as pedantically type safe as it could be, since we simply use `types.raw` for resources such as NixOS users settings which *could* be more finely delineated

closes#93.
note that this includes classes:
- `nixos`
- `nixosTest`
- `nixops4Resource`
- `nixops4Deployment`
.. and my (made-up, as per the [docs](https://ryantm.github.io/nixpkgs/module-system/module-system/#module-system-lib-evalModules-param-class)):
- `nix-unit`
- `package`
.. while i did not manage to cover:
- service tests, given `pkgs.nixosTest` seemed to not actually like `_class = "nixosTest"` (?!)
... nor #93's mentioned destructured arguments for that matter, as per Fediversity/Fediversity#93 (comment) - let me know if that is still desired as well.
