Before #51417, trimUnreferencedReaders in this test was a noop as the default translog retention policy was 512MB and 12h, which was long enough to keep all translog files. Two problems in this test: - We do not consider any failure while trimming unreferenced readers as a tragedy. - We should clear the synced list before calling trimUnreferencedReaders. Relates #51505 Closes #51694

We no longer need to retain the extra translog for peer recovery as we have switched using Lucene index exclusively in 8.0. This change removes the translog retention policy.
I think we can also remove the async trim translog task. I will do it in a separate PR.
