      Description

      We have the GET /hawkular/metrics/gauges/{id}/data endpoint which queries for data points and optionally does down sampling, which is the process of reducing the number of data points for a given time interval. One or more aggregation functions are used to compute the new data points. We have been informally referring to this processing as bucketing, but I prefer to use the term down sampling because it is the term commonly used in other monitoring systems and because our use of the term bucketing or buckets is becoming overloaded. We need to provide this same functionality across multiple metrics where the metrics that are queried is determined by a tag query filter. MetricsService.findMetricsWithFilters already provides the tag querying functionality that is needed.
