the campaign/:id/margins endpoint still returns the legacy xml->json converted format:

      "prop": [
        {
          "value": "123456",
          "name": "campaign_id"
        },
        {
          "value": "2017-01-19T00:00:00",
          "name": "margin_date"
        },
        {
          "value": "85.0000",
          "name": "margin_pct"
        },
        {
          "value": "2017-01-25T00:43:26",
          "name": "created_on"
        },
        {
          "value": "2017-01-25T00:43:26",
          "name": "updated_on"
        }
      ],
      "name": "campaign Margin 2017-01-19",
      "id": 1542715,
      "type": "campaign_margins_calc"
    }

we'll need this to be consistent with the rest of the json responses before we can add support.
