Feature Request: publish package on a private pypi server?

Hello, my organization uses nbdev extensively. To use the packages in Colab, we need to clone and install the repo each time we wish to use the package that we've developed in Colab. `nbdev_release_pypi` by default publishes the package to the public pypi server, is there any plan to add a feature to publish the package to a private pypi server?

maybe additional params can be added in the `settings.ini` to make this possible? Any thoughts on this? @hamelsmu @seeM ?
