There's a few things that would need to be enabled in order to reuse
some of this work.  We'll need to add the ability to generate a report
on the puppet run[0]. And then we'll need to be able to capture it[1]
somewhere that we could then use that parsing code on.  From there,
just rerunning the installation would be a simple start to the
idempotency check.  In fuel, we had hacked in a special flag[2] that
we used in testing to actually rerun the task immediately to find when
a specific task was not idempotent in addition to also rerunning the
entire deployment. For tripleo a similar concept would be to rerun the
steps twice but that's usually not where the issues crop us for us. So
rerunning the entire installation deployment would be better as we
tend to have issues with configuration items between steps
conflicting.
