    Description

      Periodically, we should rerun the logic in ReplSetImpl::getMemberToSyncTo(). The ping times may have changed since last check, or the oplog staleness within the cluster may have changed such that a different node is now much more up-to-date.
      Currently we only do this check when the cluster state changes.
