Add Aggregation transformation also for CDS Current Environments List Records connector

[TPertila]

Common Data Service List Records connector has handy Aggregation transformation property. It makes our flows much simplier for example in cases when there is need to sum values from n records. 

Please provide this functionality also for CDS (Current Environment) list records action.

This is a highly useful feature in the classic CDS connector. One of the few parity issues that I hope will be resolved between the two connectors.
