Fixes: SCYLLADB-1416 Adds an optional replay_position to the (transient) replay history, and provides this (when available) to tombstone_gc gc_min_time callback checks. When updating repair history, we set a commitlog cleanup record preventing replay of data lower than current flush position, and add said flush position to the local repair history. The idea is that when set (not zero rp), this can be used to limit the commitlog segments from which we check timestamps, potentially filtering out older ones. This will allow tombstone gc repair case to potentially filter out some commitlog data, and thus reducing the retention window for tombstones. Note: this does not affect the persisted repair history, only node-local, transient data. Feature improvement. No backport needed.
