JFG-651 create aggregators required to store monitoring metrics

Actually we need 2 aggregators for Monitoring parameters : 
    - AvgMetricAggregatorProvider (that we already have) for non cumulative monitoring parameters. 
    - MaxByCountAggregatorProvider (take max value on interval and divide on number of points) for cumulative monitoring parameters. 
                 
p.s. Max - due to MonitoringAggregator - actually we need LastInputByCountAggregatorProvider.
