Code review comment for lp:~frankban/juju-quickstart/more-cloud-providers

I agree that some of the points Rick brings up - notably destroying an
environment - are worth considering, though I think they may be worth
their own branches. However, if that's the case, then I think we should
withhold the move to 1.0.0 until the destroy confirmation is made, since
that's potentially big. That means, either include that here or push to
another branch with 1.0.0; otherwise, LGTM! Thanks for the work!
