Code review comment for lp:~thumper/juju-core/fast-lxc-no-apt-upgrade

I'm not fully across the finer details about lxc cloning. I think this
looks good. Perhaps a little more test coverage though. Specifically:
1. EnsureCloneTemplate behaves correctly if called when a template
already exists
2. The cloud init contents are devoid of apt stuff

Is there a helper function for str -> bool?

does this need to be exported?

Should we be checking (some key aspects of) the contents of the
template?
