Notable Changes
---------------
* The "BlueStore zero block detection" feature (first introduced to
Quincy in #43337) has been turned off by default with a new global
configuration called bluestore_zero_block_detection. This feature,
intended for large-scale synthetic testing, does not interact well with
some RBD and CephFS features. Any side effects experienced in previous
Quincy versions would no longer occur, provided that the configuration
remains set to false. Relevant tracker:
https://tracker.ceph.com/issues/55521
* telemetry: Added new Rook metrics to the 'basic' channel to report
Rook's version, Kubernetes version, node metrics, etc. See a sample
report with ceph telemetry preview. Opt-in with ceph telemetry on.
For more details, see: https://docs.ceph.com/en/latest/mgr/telemetry/
* Add offline dup op trimming ability in the ceph-objectstore-tool.
Relevant tracker: https://tracker.ceph.com/issues/53729
* Fixed a bug with cluster logs not being populated after log rotation.
