Expose this information to replication manager to reset the replication token for this partition since we
recovered from partial log segment. When we persist replication tokens, we intentionally make delays so we don't
persist tokens that are not having all the data in log segment persisted, so we shouldn't have to reset the
replication token, but this is safe.
