Add CLI entry point umd

- add the following file:
  + src/urban_meal_delivery/console.py => click-based CLI tools
  + tests/test_console.py => tests for the module above
- add a CLI entry point `umd`:
  + implement the --version / -V option
    to show the installed package's version
  + rework to package's top-level:
    * add a __pkg_name__ variable to parameterize the package name
  + add unit and integration tests
- fix that pylint cannot know the proper order of imports in the
  isolated nox session
