Head2Head markets

Head2Head markets are ordinary markets with the two head2head competitors being the two outcomes. Each outcome’s id is the competitor id for that outcome.

Head2head markets are currently associated with a broad sr:simple_tournament that is used for all head2head offers for the same sport no matter what actual race it is (just like the LCoO feed works today).

This will change, and the head2head markets will be associated directly with the exact race-event.
