This refactors the existing premium list functionality into the new class StaticPremiumListPricingEngine, which implements PricingEngine. A backfill @OnLoad is provided to default existing Registry entities into the static implementation. For now there is just this one implementation. Dagger map multibinding is used to generate the total set of allowed pricing engines, and allows other parties to plug in their own implementations. The pricing engine is a required field on the Registry object. If you don't want a particular Registry to actually have a premium list, then use the static pricing engine but don't actually set a premium list. A subsequent CL will refactor the Key<PremiumList> field on the Registry entity class to be handled solely by the StaticPremiumListPricingEngine implementation. Going forward, all configuration and implementation details that are specific to a given pricing engine should be handled by that pricing engine, and not as fields on the Registry object. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=121850176
