pytest: support for poetry ? about circleci-orbs

[jhillacre]

We haven't used poetry too much, having just crawled out of requirements.txt into pipenv.

If the changes are straightforward, I don't see why we wouldn't take a PR. As the changes get more complex, the lack of tests on orbs for functionality we don't personally use could be a problem.

I'm surprised anyone would be using our orbs as is. While a public repo, since CircleCI private orbs didn't exist when we started, we do assume some @arrai-innovations specific related to uploading coverage/badges, repo architecture, and server environments regarding executors.

Are you all using a wrapping orb and splicing the commands yourself, or are you just using the jobs as is?
