Try out poetry

[goodboy]

Last time i tried one of these "super packaging" projects it was
pipenv #82, and it didn't go well.

Given we're likely moving all infra development and deploys to nixos,
and given the issues with the normal python packaging nightmare and how
it conflicts with nixos style profiles / environments i'd like to give
poetry a try:

Wait, why try one of these projects again?

• it's been a long while, likely this project space has matured and
  we're very happy with other projects we're using from the same
  author: pendulum, tomlkit

• the main pain point we had with pipenv (IIRC) was git deps:

  • https://python-poetry.org/docs/dependency-specification/#git-dependencies

• nixos has a bunch of 3rd party wrappers for supporting conversion to
  nix hybrid packaging and dev envs:

  vox virt envs that will only work if there are no sh-lib deps:
