Can unearth read from ~/.pip/pip.conf ?

Is your feature request related to a problem? Please describe.
I'd like unearth to implicitly pick up the internal index url from pip.conf

This would also help our company port to PDM 2.0.

pip has three layers of OS-dependent configuration files and supports overriding via env vars. Ref: https://pip.pypa.io/en/stable/topics/configuration/

It is over-complicated to read such configurations which are not part of unearth itself, unless we hard depend on pip. IMO it is not worth the effort. @Hnasar PDM 2.0 has its own configurations of PyPI URLs, why would you still rely on the pip conf if you are going to port to PDM?

[Hnasar]

@frostming at Beta we have ~50 python projects. Previously:

1. we had all devs configure a pip.conf so that pip and pdm used our internal package registry (with netrc for listing credentials)
2. For CI we set a environment variable for the index url

For 1: If PDM 2.0 doesn't read pip.conf then I will need to go through and add tool.pdm.source to all the pyproject.toml files.

For 2: I can easily add another CI variable for PDM's index url, but I really just want pip and PDM to always use the same url.

So this change is a small hassle for users with many repos. I wish pep 621 had a standard configuration for the index url.

@Hnasar You can configure your PyPI mirror in pdm.conf and it will be used by all projects - wouldn't that solve your problem?
