[Distutils] Automation for creating, updating and destroying a TUF-secured PyPI mirror

[Trishank Karthik Kuppusamy]

Hello PyPI,

Hope attendees had a great time at PyCon 2013! We certainly enjoyed 
presenting to you our lightning talk on securing PyPI with TUF 
(https://www.youtube.com/watch?v=2sx1lS6cT3g).

Since then, we have been busy improving TUF and implementing machinery 
to automatically secure PyPI with TUF:

You may also have noticed that the root metadata for our prototype 
mirror of PyPI+TUF expired yesterday. This aligns nicely with our plan 
for switching our hand-maintained PyPI+TUF mirror with the automatic 
one. We expect to have it ready very soon, and until then, we certainly 
welcome your first impressions on our automation. You could try it on 
your machine right away!

Finally, we are working continuously on improving TUF, especially on 
ensuring that the metadata scales with data. We welcome your feedback on 
these issues and more (https://github.com/akonst/tuf/issues?state=open).
