Add CM360 Rich Media Fields - Interactive Impressions#1503

I’d like to have the Interactive Impressions field added from CM360. It is a Rich Media field: https://support.google.com/campaignmanager/table/6170532?hl=en#query=rich%20media

Also Interactive Impressions from DV360 - https://support.google.com/displayvideo/table/3187025?hl=en#query=interactive%20impressions
