Description of change

Adding GDPR support to Smart's prebid adapter.

Please use the following test parameters:

          {
            code: 'div-gpt-ad-1460505748561-0',
            sizes: [[300, 250]],  // a display size
            bids: [{
              bidder: "smart",
              params: {
                domain: 'http://ww251.smartadserver.com',
                siteId: 207435,
                pageId: 896536,
                formatId: 62913
              }
            }]
          }

As a result Smart's adapter should send acquired GDPR params in the POST message.
