* `AfterSetFeedConfig(ctx sdk.Context, feedConfig *FeedConfig)`
  * called after feed config is created or updated
* `AfterTransmit(ctx sdk.Context, feedId string, answer math.LegacyDec, timestamp int64)`
  * called when info is transmitted
* `AfterFundFeedRewardPool(ctx sdk.Context, feedId string, newPoolAmount sdk.Coin)`
