Project cleanup

[cidrblock]

This ticket is used to track QA tasks being performed as part of code cleanup and

• Where they existed docstring were converted to google style
• Cspell replaced codespell
• All the tooling configuration parallels the VsCode extension list so that should make development much easier w/o surprises
• Tests were renamed and restructured
• Docstring and type hints are now required and checked
• Finalize mypy types usage

This brings molecule in line with some of the other ansible developer tools projects so it should be easier to move between them. Those include ansible-creator, ansible-dev-environment, ansible-dev-tools, pytest-ansible and tox-ansible. These should all use the same toolset and have a very similar CI and developer configuration moving forward.

If you are a VsCode user, try out the @recommended extensions, I think you will like the list, experience and feedback through the problems tab while coding.

We still have work to do on ansible-navigator, ansible-compat and ansible-lint but I do hope you like the cleaner house. If not please open an issue or comment below and we can figure out where we went wrong.
