Description of change

Pre-auction filters and pbadslot support

1. The pbAdSlot attribute is added to the Prebid Ad Unit in the First Party Data context

var AdUnit={
   code: "40989gjr9e98ajrosiero",
   fpd: {
     context: {
        pbAdSlot: "/1111111/homepage/med-rect-2"
     }
   },
};

2. define pre-auction filter function

var setPbAdSlot = function setPbAdSlot(adunits) {
    console.log('setPbAdSlot called');
    // ... logic to find and set fpd.context.pbAdSlot for each AdUnit ...
};
pbjs.onEvent('onBeforeRequestBids', setPbAdSlot);

3. The Prebid Server Bid Adapter must pass the Prebid AdSlot through the OpenRTB request in imp[].ext.context.data.adslot

{
  imp: [{
    ext: {
      context: {
        data: {
          adslot: "/1111111/homepage/med-rect-2"
        }
      }
    }
  }]
}

Sorry @idettman - we added in an 'fpd' level at some point that didn't get reflected in pbAdSlot.
