[Merge] lp:~allenap/maas/effing-download-cache into lp:maas

 

Gavin Panella has proposed merging lp:~allenap/maas/effing-download-cache into lp:maas.

Requested reviews:
  Launchpad code reviewers (launchpad-reviewers)

For more details, see:
https://code.launchpad.net/~allenap/maas/effing-download-cache/+merge/110534

This removes the need for the faulty zc.buildout bootstrap.py script. Instead it creates a virtualenv and uses pip to install zc.buildout from source.

Part of this required removing the allowed-eggs-from-site-packages setting in buildout.cfg. This isn't really needed - I think we always want to use the system package if it's available - and I believe this option won't be available in buildout 2. If we need to test using a package version different to the system package it can be installed using pip.
