Bug description:
  [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
