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.

Following Fediversity/Fediversity#478 (comment), here is a PR that plugs the infra's `vmOptions` and `nixosConfigurations` outputs into flake checks, instead of calling random Nix commands from the CI. There is still a bit of magic in the CI, but that's because we don't have yet a Nix-aware CI that exposes one job per flake check.

This PR contains a bunch of small fixes having to do with infra code. The goal is not to fix everything as that would require a full rewrite. Instead, we fix just what is necessary to get some testing going on. Once that is available, we will be able to work on a full refactor with more guarantees. Something of note is that most of the difficulty was to find code that would make both `nixops4 apply` _and_ `nix build .#nixosConfigurations.<machine>` happy. The takeaway is that the tests that we are adding now will not catch a whole class of tests having to do with how NixOps4 wires up the resources. Still, this is probably less significant as we are supposed to use NixOps4 every now and then.
The commits should be read separately.

this test is still borked as per #33.
the intent would be to get this test on a feature branch pertaining to that issue - the point being we should be able to rely on CI's boolean result for detecting (newly induced) regressions.

Closes#277
Same as #329 but where we run the FediPanel and interact with it via a browser
instead of running NixOps4 directly.

Closes Fediversity/Fediversity#276
This PR adds a CLI deployment test. It builds on top of Fediversity/Fediversity#323. This test features a deployer node and four target nodes. The deployer node runs `nixops4 apply` on a deployment built with our actual code in `deployment/default.nix`, which pushes onto the four target machines combinations of Garage/Mastodon/Peertube/Pixelfed depending on a JSON payload. We check that the expected services are indeed deployed on the machines. Getting there involved reworking the existing basic test to extract common patterns, and adding support for ACME certificates negotiation inside the NixOS test.
What works:
- deployer successfully runs `nixops4 apply` with various payloads
- target machines indeed get the right services pushed onto them and removed
- services on target machines successfully negotiate ACME certificates
What does not work: the services themselves depend a lot on DNS and that is not taken care of at all, so they are probably very broken. Still, this is a good milestone.
Test it yourself by running `nix build .#checks.x86_64-linux.deployment-basic -vL` and `nix build .#checks.x86_64-linux.deployment-cli -vL`. On the very beefy machine that I am using, the basic test runs in ~4 minutes and the CLI test in ~17 minutes. We know from Fediversity/Fediversity#323 that the basic test runs in ~12 minutes on the CI runner, so maybe about an hour for the CLI test?

This PR adds a basic deployment test to the repository. This test will, in a NixOS test, run a deployer VM and a target VM, and check that we manage to run `nixops4 apply` on the deployer VM to change things on the target VM. The ideas are all @roberth's and this test has been extremely heavily inspired by https://github.com/nixops4/nixops4-nixos/blob/main/test/default/nixosTest.nix.
