Continuing the Python 3 transition
We took a bit of a break in active Python 3 porting for Saucy, but now that we're in the 14.04 LTS cycle, we want to concentrate again on this important task. There are three general categories:
* Remove Python 2 from the Touch images
* Remove Python 2 from the default desktop images
* Remove Python 2 from the default server images
Much has been done by upstreams and Debian in the meantime, so now we need to re-evaluate the work needed for Trusty.

Whiteboard
Python 2 autopilot will be provided by the autopilot-legacy package, which will be eliminated asap in utopic. autopilot package will only provide Python 3.
Server pulls in Python 2 because of byobu, landscape-common, and vim. For vim we have: http://
Desktop has more dependencies.

== AUTOPILOT migration to python3 ==
* Keep emulators bilingual for now (Python 2 and 3).
* Port all tests to Python 3.
* Eventually we will drop support for Python 2 emulators.
* Change Build-Depends for unported apps to use autopilot-
Upload debs and clicks using python3:
- for debs, drop /usr/lib/python2.7 tests and ship them in /usr/lib/python3
- for clicks, specify x-test:
