`RaftMetrics::millis_since_quorum_ack` is the interval in milliseconds since the last timestamp a quorum acknowledged. This duration is used by the application to assess the likelihood that the leader has lost synchronization with the cluster. A longer duration without acknowledgment may suggest a higher probability of the leader being partitioned from the cluster.
