.Corrupted dups entries of a PG Log can be removed by off-line and on-line trimming Previously, trimming of PG log dups entries could be prevented during the low-level PG split operation, which is used by the PG autoscaler with far higher frequency than by a human operator. Stalling the trimming of dups resulted in significant memory growth of PG log, leading to OSD crashes as it ran out of memory. Restarting an OSD did not solve the problem as the PG log is stored on disk and reloaded to RAM on startup. With this fix, both off-line, using the `ceph-objectstore-tool` command, and on-line, within OSD, trimming can remove corrupted dups entries of a PG log that jammed the on-line trimming machinery and were responsible for the memory growth. A debug improvement is implemented that prints the number of dups entries to the OSD's log to help future investigations.
