updates for Python 3.11

[vbanos]

If we are dropping support for python <3.8, we can make many more improvements. E.g. from __future__ import absolute_import is not needed any more.

Also, all class definitions that are like class PlaybackIndexDb(object) could be become class PlaybackIndexDb

Finally, we'll be able to use f-strings which improve readability a lot (that's a big change, I don't suggest doing it now).

What is the python version used when you run tests/run-all-tests.sh I see libpython2.7-dev libpython3-dev and a very old pip version pip-9.0.1.tar.gz in https://github.com/internetarchive/warcprox/blob/Py311/tests/Dockerfile Maybe you need to update this as well.

The benchmarks use a very old version of aiohttp. https://github.com/internetarchive/warcprox/blob/Py311/benchmarks/requirements.txt Does it work with py311 ? Maybe you can update it as well https://pypi.org/project/aiohttp/#history

I got this branch in my computer, I installed using pip install . in my existing py38 venv and got the following error when trying to run it. Thank you.

It looks like pip failed to install the updated dependency, rethinkdb v.2.49, from doublethink.

I wonder if you have better luck creating a new virtualenv?

A draft update to the benchmarks is in PR #193

[galgeek]

An earlier PR, #181, updates warcprox tests for github actions. It includes output from running against Python 3.11.2 that look good.

I created a new virtualenv and pip install . worked. Thank you.
