treewide: drop poetry2nix

[K900]

Description of changes

poetry2nix in-tree was broken in a pretty major way for a while now, and the only remaining consumers in nixpkgs itself were NixOps versions. So, drop NixOps stable (it's on Python 2, which is very dead), rework NixOps unstable to use nixpkgs dependencies, and finally drop poetry2nix itself.

I've taken the liberty to add upstream maintainers as maintainers to the respective NixOps plugins - if you'd like to be excluded, please say so.

How's the in-tree poetry2nix broken? And why can't we just update it to fix it?

[K900]

It was broken by the Python bootstrap changes, and we don't really want to update it because the out-of-tree version is generally better, because it has a lot more overrides and adds them a lot faster. We also don't want to encourage new poetry2nix consumers in-tree.

This is a release manager seal ✔️.

[K900]

Marking as draft to prevent accidental merges.

[K900]

Fixed eval error.

What's the reasoning behind adding these nine by default rather than all of them?

[K900]

That's what the previous version of the expression did.

[K900]

Updated to latest version of nixops with all the fixes, also added updateScript everywhere.

[K900]

This should be good to go now, though I'd prefer to get explicit agreement from people added as maintainers before we merge.

[K900]

@Kiwi @lukebfox please respond if you don't want to be added as maintainers for your Nixops plugins' expressions in nixpkgs. (please also respond if you do want to be added)

[lukebfox]

Thanks for waiting, I'm happy to maintain my plugin's nix-expression here.

[K900]

I'm just going to merge this, and if @Kiwi wants to step down, they're welcome to. I'm really worried about this bitrotting.
