[Merge] lp:~canonical-platform-qa/ubuntu-qa-tools/dl-with-distro-info into lp:ubuntu-qa-tools

[Steve Beattie]

Review: Approve

Thanks, merged with a tweak to give a more informative error message for people who run dl-ubuntu-test-iso out of the bzr tree directly and don't have python-distro-info installed.
