Colin Watson has proposed merging ~cjwatson/launchpad:py3-shebang into launchpad:master.

Commit message:
Change #! of most python2 scripts to python3

Requested reviews:
  Launchpad code reviewers (launchpad-reviewers)

For more details, see:
https://code.launchpad.net/~cjwatson/launchpad/+git/launchpad/+merge/406468

I skipped a couple of utilities that still need some work and that don't import anything from Launchpad's virtualenv.
-- 
Your team Launchpad code reviewers is requested to review the proposed merge of ~cjwatson/launchpad:py3-shebang into launchpad:master.
