The shortest fix is to "pin urllib3<2.0":https://github.com/docker/docker-py/issues/3113.

But holy crap y'all, we currently have the Docker library we used pinned to one specific version, and I committed that pin last time I worked here, in 95253d987794df9c27db93b1b9f8be2d32229309.

I would at least like to try an upgrade. The library has a changelog that conveniently labels Breaking changes.

They supported Python 3.6 until version 6.0, we can start there.
Their minimum Docker API version is 1.21, ours is 1.35.
From a quick skim, it looks like there will be some API renames to work through, but that's it. While there are other breaking changes documented like return type changes, I didn't notice any that pertain to the images API the image cleaner uses.

As long as I haven't missed anything major this should be doable with a story point-ish.

Done in 20754-docker-py-upgrade @ c071d7aaed53241f68bad09d8dd8d20b21b8bb40 - developer-run-tests: #3761

The switch from docker-py to docker is expected, the module itself renamed. See their 2.0.0 changelog
The updates to the tests are mostly to get mocks to match API changes in the module.
Because there are no "real" tests, I did run the service manually on my system, and it seemed to work fine. It removed containers, it deleted images, it followed some events.
