Great idea.

We did something similar from support side with https://citellus.org not just
for upgrades but also for identifying ongoing issues also from sosreports.

Wes did a POC at https://review.openstack.org/#/c/553571/ for integrating it too.

So if we could even reuse them somehow, that will be great.
