Make configuration binding serializers generic

[elandau]

ConfigurationProvider must currently be extended as new types are supported. A more extensible approach would be to have a generic PropertyBinder interface that can be installed as part of a multibinding. When mapping a configuration the ConfigurationProvider will iterate though the set of PropertyBinder's to determine the most appropriate binder. A new serializer can be added as a new binding without having to modify the ConfigurationProvider interface.

public interface PropertyBinder {
}

public class BinderModule extends BootstrapModule {
    public void configure(BootstrapBinder binder) {
        Multibinder<PropertyBinder> binders = Multibinder.newSetBinder(binder, PropertyBinder.class)
        binders.addBinding().to(StringPropertyBinder.class);
        binders.addBinding().to(DoublePropertyBinder.class);
        binders.addBinding().to(PropertiesPropertyBinder.class);
        binders.addBinding().to(ObjectPropertyBinder.class);
        binders.addBinding().to(IntegerPropertyBinder.class);
        binders.addBinding().to(BooleanPropertyBinder.class);
        binders.addBinding().to(InjectingPropertyBinder.class);
        ....
    }
}
