Nhat Nguyen df46848fb0 Migrate peer recovery from translog to retention lease (#49448) ... Since 7.4, we switch from translog to Lucene as the source of history for peer recoveries. However, we reduce the likelihood of operation-based recoveries when performing a full cluster restart from pre-7.4 because existing copies do not have PPRL. To remedy this issue, we fallback using translog in peer recoveries if the recovering replica does not have a peer recovery retention lease, and the replication group hasn't fully migrated to PRRL.
