Extract premium pricing to a PricingEngine interface

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.
