Description

Ambari metrics grafana datasource currently doesn't allow users to customize the time window for which the aggregator is applied.

This feature would allow have a separate text field in Ambari metrics grafana datasource that will allow users to override the default aggregation window i.e. group by time which is used for functions like avg, sum, min, max etc. E.g. if the user wants to granularity by the minute we can configure the time window for 1m and not loose resolution in the graph. 

This increases the number of datapoints rendered in grafana therefore it is an advanced feature since theoretically a user may trigger a query that slows the UI.
