Add cumulative and gauge to aggregator transformer

Currently, the aggregator transformer just sums up the volumes of all
aggregated samples.

This patch improves it so it returns just the latest volume for cumulative
meters and the average of volumes for gauge meters.

DocImpact: Aggregator transformer now works for gauge and cumulative as well
