QFE: AppNexus inventory quality filtering
 * Quality filtering missing from current campaign profile template
 * Adding the following should provided the needed filtering:
        ""trust"":""appnexus"",
        ""allow_unaudited"":false,
        ""intended_audience_targets"":[""general"",""children"",""young_adult""],
 * use_inventory_attribute_targets and inventory_attribute_targets are being left unchanged
   - default values of "false" and "[]" equate to "Allow All" in AppNexus console campaign inventory UI
   - If inventory attributes are selected as measures then they will be included and the use_ flag set true
