setRewardOracle

function setRewardOracle(address reward, IEACAggregatorProxy rewardOracle) external

Sets an Oracle contract to enforce rewards with a source of value.

At the moment of reward configuration, the Incentives Controller performs a check to see if the reward asset oracle is compatible with IEACAggregator proxy. This check is enforced for integrators to be able to show incentives at the current UI without the need to setup an external price registry
