Test infrastructure, packaging, etc. needs overhaul

[tony]

Here is all a user should need to bootstrap themselves:

poetry install

And to test:

poetry run py.test

It seems that tox is set as a requirement, not a supplement, to testing on the django-robots - blocking any hope of accomplishing even basic tasks.

CI could use test matrix to get django

This is needed for #133 and for future maintainers #135

Note: As-is, of 5.0 at 77b980c, here's how tests can be ran:

env PYTHONPATH=. DJANGO_SETTINGS_MODULE=tests.settings django-admin test robots -v2

I disagree that tox is a blocker for any of this, but I see why you'd feel that way since currently the test setup isn't using tox-gh-actions that allows mapping GitHub action matrix items to tox configuration and vice versa. I'd recommend doing that before flipping a table and go with Poetry.

@jezdez I am fine with that.

I will close this and note the preference for https://pypi.org/project/tox-gh-actions/
