   * Add a latency, rate and total sensor for a specific operation, which will include the following metrics:
   * <ol>
   * <li>average latency</li>
   * <li>max latency</li>
   * <li>invocation rate (num.operations / time unit)</li>
   * <li>total invocation count</li>

   * it will be counted as one invocation of the operation, and hence the rate / count metrics will be updated accordingly;
   * and the recorded latency value will be used to update the average / max latency as well. The time unit of the latency can be defined
   * by the user.
   *
   * Note that you can add more metrics to this sensor after created it, which can then be updated upon {@link Sensor#record(double)} calls;
   * but additional user-customized metrics will not be managed by {@link StreamsMetrics}.
   *
   * @param scopeName          name of the scope, which will be used as part of the metrics type, e.g.: "stream-[scope]-metrics".
   * @param entityName         name of the entity, which will be used as part of the metric tags, e.g.: "[scope]-id" = "[entity]".
   * @param operationName      name of the operation, which will be used as the name of the metric, e.g.: "[operation]-latency-avg".
   * @param recordingLevel     the recording level (e.g., INFO or DEBUG) for this sensor.
