Project code Formatting

[talebzeghmi]

Goal: Consistent Metaflow project code.

Creating an issue to introduce Metaflow project code formatting and verification as part of the CICD process.

Ensuring that the whole code base, including plugins, follow the same style makes it easier to read and easier to write plugins in a consistent style.

Thanks for opening the issue. There is a related issue #218 for checking code styles. It's something that we plan to get to soon.

Awesome, let me know if I can help!
This task is for formatting and updating the Metaflow core code style (example: https://github.com/Netflix/metaflow/blob/master/metaflow/cli.py)
