Parsing setup.cfg files

[canassa]

Hello,

Setuptools supports configuring libraries using only the setup.cfg nowadays., see:

https://setuptools.readthedocs.io/en/latest/setuptools.html#configuring-setup-using-setup-cfg-files

It would be nice if pip-upgrader could parse that aswell. I think that it should limit itself for dependencies are pinned e.g.:

[options.extras_require]
tests =
    flake8==3.7.8
    isort==4.3.21
    mypy==0.711
    pytest==5.0.1
    pytest-cov==2.7.1
    black==19.3b0
    pre-commit==1.17.0
    bump2version==0.5.10

And not so much for the version ranges.

Let me know if this is a welcome addition, I could maybe contribute to the project myself 😁

Thanks!

It would be a great addition. 💪

I'm also intending to remove package installation feature (ie: --skip-package-installation), and just update the requirtements/setup.cfg files with the new versions.
This would allow me to implement support for Pipenv (nowadays I'm using pipenv/Pipfile for managing packages and virtualenvs).

Since I recently migrated all my reqs.txt files to setup.cfg pip-upgraded become useless as it fails to find any kind of requirements. It would be great to add support for setup.cfg as this is the future.

An identical use-case is tox and deps, so an implementation should have a set of patterns for sections+keys like [options.extras_require]*, [testenv*]deps, and so on. The filename should be passed like any requirements file, so that tox.ini could also be used.
