      Public constructor.
      Parameters:
      periodicStatistics - Where to send metrics about aggregation computations.
      emitter - Where to send the metrics data.
      clusterHostSuffix - The suffix to append to the hostname for cluster aggregations.
      reaggregationDimensions - The dimensions to reaggregate over.
      injectClusterAsHost - Whether to inject a host dimension based on cluster.
      aggregatorTimeout - The time to wait from the start of the period for all data.
      periodicMetrics - The PeriodicMetrics instance.
