Merge lp://qastaging/~oddbloke/simplestreams/example-sync into lp://qastaging/~smoser/simplestreams/example-sync

i think there are unrelated/unintended changes here that don't fit the commit message "Update to use simplestreams from git".

I think we'll be able to `sh -x $scriptname` for both of these where we

trusty doesn't have the Python 3 OpenStack libraries in the archive, so
using Python 2 is required.
