One-liner to run pytest and lint under Docker

[gabriel-v]

Setting up an environment for the first time (following https://insitro.github.io/redun/developing.html) directly on the host has quite a few setbacks:

• make setup
  • does not install/check for Java, needed for some federated/spark tests, installed implicitly in Ubuntu but not in Debian; this is not mentioned
  • need to find python3.10 or older, when package manager might have only 3.11
  • docs outdated; makefile rules make mypy and some others no longer exist. If this was a single entry script, docs would not need update as often

I see you already use docker-compose for the database, both in tests and examples. Why not use a docker/compose container to run the tests & examples too? The packaged dockerfile could serve as example for anyone trying to adapt it to their own hosts / containers.

So a new developer could just run ./pytest.sh -k filter --pdb and test what they are trying to patch in 5min, with 100% parity on the CI

I have a PR with some example scripts to start a discusison
