[$] New CPython workflow issues

As part of a discussion in 2014 about where to host some ofthe Python repositories, Brett Cannon was delegated the task of determining where they should endup. In early 2016, he decided that Python'scode and other repositories (e.g. PEPs) should land at GitHub;at last year's language summit, he gave an overview of where thingsstood with a few repositories that had made the conversion. Since thattime, the CPython repository has made the switch and he wanted to discuss some of theworkflow issues surrounding that move at this year's summit.
