Comment 17 for bug 1830736

So, given that the process is different there is no need to add journal in:
Ceph::Osd {
      cluster => $cluster_name,
      cluster_uuid => $cluster_uuid,
    }

And please don't change it as it should no longer create the default collocated journal partition on the OSD, which is still needed even if users configure external journals (for failback).
