feat(back): #0 allow mypy 0.971

- In this version of mypy, mypy is able to pick
  the type stubs from the PYTHONPATH,
- Allow picking the new version as a feature flag
  so that we can migrate universe to the latest
  version product by product
- Dont document this feature as I plan to remove
  it before the next makes release
