Hello @potiuk 

I believe you wrote this script - [`prepare_provider_packages.py`](https://github.com/apache/airflow/blob/master/dev/provider_packages/prepare_provider_packages.py).

I am wondering if there is any reason why you did not use the standard library - [`argument.ArgumentParser`](https://docs.python.org/3/library/argparse.html) in this script?
https://docs.python.org/3/library/argparse.html
https://github.com/apache/airflow/blob/550395192929f86376151b4385cea6b8dfb76e8e/dev/provider_packages/prepare_provider_packages.py#L1518-L1552

This makes the code overly complex and, by the way, more prone to errors e.g.  ``usage()`` method describes the `--version-suffix-for-pypi` parameter, but we changed its name to `--version-suffix`.

What do you think to rewrite this script to use the standard library? Do we have a requirement that prevents this? I think of something similar to [my gist](https://gist.github.com/mik-laj/ff008718fc6cec9fe929731b8c62d6f8).
