Public bug reported:
Opening to track upstream issue https://tracker.ceph.com/issues/52804
Issue is HybridAllocator tail latency observed in clusters with NVMe
OSDs after upgrade to Octopus from Mimic.
The allocator default was switched to "hybrid" from "bitmap" by
upstream. Switching the OSDs back to the bitmap allocator removed the
observed tail latency.
