Ceph unstable when upgrading from emperor (v0.72.2) to firefly (v0.80-rc1-16-g2708c3c)

Well, we haven't finished diagnosing #8232 yet ? I think it's actually
different from #6992 ? so I can't really tell you what will fix it!
Restarting the hosts might. If not, I'd love for somebody to reproduce
this with "debug ms = 10" enabled so I can get a log and see what's
causing it.
