qa/cephadm: do not start upgrades from Octopus

now that we officially have v18 in main the upgrade
will fail if upgrading from Octopus (v15) to main
because they are now considered 3 major releases apart

Additionally adding more debugging to the end
of the upgrade tests as something like `ceph health detail`
can be very useful to see at the end of failed
upgrade tests
