- add pre-commit hooks:
+ run `nox -s lint` on staged *.py files
+ run common pre-commit hooks for validations that could not be
achieved with tools in the develop environment so easily
- add pre-merge hook:
+ run `nox -s _pre-commit-test-hook` before merges
* ignores the paths to staged files
passed in by the pre-commit framework
* runs all test cases instead
