[Bug 1978913] [NEW] [SRU] ceph-osd takes all memory at boot

[nikhil kshirsagar]

Public bug reported:

[Impact]
ceph-osd takes all memory at boot

[Test Plan]
https://tracker.ceph.com/issues/53729

[Where problems could occur]
Trimming large clusters could be time consuming.

[Other Info]
The way this is fixed is that the PGLog needs to trim duplicates by the number of entries rather than the versions. That way, we prevent unbounded duplicate growth. 

Reported upstream at https://tracker.ceph.com/issues/53729 and fixed on
master through https://github.com/ceph/ceph/pull/45529 and on octopus
through https://github.com/ceph/ceph/pull/46253
