Setup project tools and CI

[isra17]

@aviau for review.

Add tools, nox and CI.

How do I use it?

Can it be documented in the README? Can we add a Makefile with simple targets? make test, make format and make lint ?

[aviau]

Something like this?

venv:
	python3 -m venv venv
	venv/bin/pip install poetry==1.1.11 nox==2021.10.1 || (rm -rf venv && exit 1)

.PHONY: lint
lint: venv
	venv/bin/nox --session lint

.PHONY: test
test: venv
	venv/bin/nox --session tests

.PHONY: clean
clean:
	rm -rf venv
	rm -rf .nox

test does not work, it says pytest is needed, but I don't see where its installed in the github workflows.

nox effectively replace your Makefile. I can document how to do most thing.

nox effectively replace your Makefile.

Not if it requires me to have a specific version of nox and a specific version of poetry installed globally.

What happens if I have two projects that require different versions of nox or of poetry?

[aviau]

lgtm if you fix mypy not having the required dependencies and you set the nox.options.reuse_existing_virtualenvs = True option.

nox_poetry is not so useful since it build a wheel package everytime and install it, adding making most task take a few more extra seconds. I ended up running poetry install in nox and it works on my machine. It's annoying because it install every single dev dependancies for all task, but the next poetry release has dependancies groups which will solve the issue.
