[ceph] Ceph integration doesn't correctly detect `fsid` for releases after `octopus`

[dancmeyers]

Ceph changed the way they output metric information in the octopus release in 2020, and as a result the Datadog integration was updated to check if the release name was explicitly octopus, and use a different codepath if it was.

There have been multiple Ceph releases since then, all with different names, all using the new metric structure, but the Datadog Ceph integration has not been updated to keep in step with them. As a result, any release since octopus has not reported certain metrics and tags correctly as the integration is trying to treat it like a pre-octopus release instead of a newer one.
