Nine different URL-specified Python dependencies had
accumulated in edx-platform, noticably increasing the amount
time it took to install edx-platform requirements.
After many developer hours of work, we are nearly finished
converting them to PyPI-hosted depencencies:
openedx/wg-developer-experience#153
We're making these updates in hopes that we don't end
up with so many URL-specified depencencies again.
We're also updating OEP-18:
https://github.com/openedx/open-edx-proposals/pull/450
The CODEOWNERS update would mean that Arbi-BOM is notified
on all future PRs that change github.in. At the moment, edx-platform
does not *require* CODEOWNER review, so this is not a *hard* gate to
github.in changes.
