Replace pipenv with poetry. Update all dependencies

[nsoranzo]

with the updated make update-dependencies .

I don't regret Pipenv - it was better than nothing, we're regularly upgrading our dependencies now. But it was really just barely better than nothing, I'm excited to see it go! Thanks so much.

@nsoranzo I tested a rerun of make update-dependencies and it looks good but I did notice the removal of the flake8 and other linting deps from pinned-dev-requirements.txt in my rebuild. Did something go wrong here, or were these inadvertently left in? 54329f9

Yes, my mistake there. I'm reworking that part as per suggestions above, will rebase and ping you. Thanks for the feedback!

[nsoranzo]

Ready from my side.

@nsoranzo Checking building one more time locally and then I'll merge, looks good to me. There's no firm requirement for pyjwt2, so it's good to go ahead and be ready for that with tests still passing against 1.7.

Edit: Worked great. Much faster than pipenv, too! Thanks, this is a nice step forward for depenency management. I like the pyproject.toml addition, too, to keep all the tooling stuff in one spot -- I'm using the same in the black branch.
