Subject: MLIA-646 Add environment to setup pre-commit hooks

- Add new environment 'lint_setup' to set up the pre-commit hooks used
  by the environment 'lint' without running the actual tests.
- Add docker file for linting and testing to the project root.
- Add helper script 'install_python_versions.sh' for docker creation.
