I have clarified the position on python2/3 use on #ubuntu-devel.  We are
actually activly meant to avoid adding any new python2 dependancies in
both Xenial and Yakkety (Xenial was the first series we attempted to
eradicate python2).

Based on that position we should either convert this script to python3
or reject the whole series exposing it.

Also in discussions with the people doing the conversion from python2 to 3
it does not seem to add value to include the future statement in a script
only intended for use in python3.  This is of use in libraries which get
imported in either, but this is not such a library.  That said as it is a
noop there I would not object to having it there if that makes you happier.
