This eliminates the use of Objectify polymorphism for EPP resources entirely (yay!), which makes the Registry 3.0 database migration easier. It is unfortunate that the naming parallelism of EppResources is lost between ContactResource, HostResource, and DomainResource, but the actual type as far as Datastore was concerned was DomainBase all along, and it would be a much more substantial data migration to allow us to continue using the class name DomainResource now that we're no longer using Objectify polymorphism. This simply isn't worth it. This also removes the polymorphic Datastore indexes (which will no longer function as of this change). The non-polymorphic replacement indexes were added in [] ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=230930546
