This commit adds the Polymorphic annotation that can be used on types.
Serializers for polymorphic types are not selected based on the
compile-time types of configuration elements, but instead are chosen at
runtime based on the actual types of their values. This enables adding
instances of subclasses / implementations of a polymorphic type to
collections.
