This work is mostly done. The switch to trusty by default is in for
everyone now. The tox upgrade is mostly complete but won't be done
everywhere until I have completed rebuilding all of our nodepool images
and then let nodes built on the old image cycle out. This should be done
shortly.

Please do let us know if you see oddness. Happy to help work through
anything that I missed when testing this stuff.
