Other information

This adapter should eventually replace the appnexus bid adapter, but that will take a long time in reality so we're not removing the appnexus adapter at this time.

The adapter uses a new openrtb endpoint instead of the previous UT endpoint. As a result, the new adapter uses the ortb converter feature to largely manage the creation/handling the request and bid response.

There are a number of bid params from the appnexus adapter that are 'deprecated' as bid params in the msft adapter. These params however are just sourcing the information from other parts of Prebid setup (like first party data or the adUnit.mediaTypes).
