Code review comment for lp:~cjohnston/ubuntu-ci-services-itself/get-swift-image

The mechanics of this look good and I was able to test that it works (from a ticket I submitted earlier today). I would prefer that it drop the image into my current dir or support an option to specify the location.

If there are significant issues with addressing Andy's comments, then I would strongly consider approving this as it does fill a functionality gap.
