The integration test was disabled due to removing support of pre-ceph-volume
OSDs as well as OSDs on directories. Now we re-enable the tests, with the
following approach:
- The base install in Rook v1.1 with the latest mimic release that
had c-v support
- The upgrade goes from v1.1 to Rook v1.2 then Rook master
- The final upgrade step is from mimic to nautilus

For efficiency the skipUpgradeChecks flag is added.
Logs are also collected between each upgrade step to improve
troubleshooting.
