Requests for PyPI packages that are not found on GitLab should be forwarded to pypi.org
Problem to solve
Python developers often use a combination of private, in-house built packages and packages that are publically available in the public PyPI registry.
However, we do not currently help users with pulling packages from this popular, remote repository.
Intended users
Proposal
When a user tries to download a PyPI package using their Project/Group/Instance-level endpoint and the package is NOT found, forward the request to pypi.org and, if possible, download the package.
Further details
This feature is part of our effort to deliver a virtual registry for the PyPI repository that will proxy and cache requests for packages outside of GitLab.
