Description

When authenticating against an external pypi server using a requirements.txt pip no longer uses the credentials supplied in the ~/.pip/pip.conf.

Expected behavior

Pip should use the credentials from the ~/.pip/pip.conf file to pull the packages from the pypi server.

How to Reproduce

## This works.

pip install pip==20.2.4
pip install -r requirements.txt
Defaulting to user installation because normal site-packages is not writeable
Looking in indexes: https://pypi.org/simple, https://pkgs.dev.azure.com/XXX/global/_packaging/XXX/pypi/simple

## This no longer works using pip >=20.3

pip install pip --upgrade
pip install -r requirements.txt

Hi

With Azure Devops we use a Personal Access Token, below is my pip.conf.
