[Distutils] Replacing pkg_resources with distlib in pip

[Marcus Smith]

Hello Vinay:
I would say get it up to date, and then submit a pull.
We can discuss details in the pull and see the travis results.
It doesn't have to be final or an immediate merge candidate to submit a
pull for discussion.
As for considering it for an upcoming pip milestone that's something we/you
can bring up on the pypa-dev list.
