Reflection-free binding to @ConfigurationProperties

[dsyer]

Might need some changes in Spring Boot, but progress can probably be made by generating a BeanPostProcessor that knows about all the @ConfigurationProperties in the classpath.

Added a new interface:

public interface PropertiesBinder<T> {

	T bind(T bean, Environment environment);

}

user registers instances with the InfrastructureUtils, e.g.

public class PropertiesBinderInfrastructureProvider implements InfrastructureProvider {

	@Override
	public Collection<? extends ApplicationContextInitializer<GenericApplicationContext>> getInitializers(
			GenericApplicationContext main) {
		return Arrays.asList(context -> InfrastructureUtils.registerPropertyBinder(context, ServerProperties.class,
				new ServerPropertiesPropertiesBinder()));
	}

}

The "func" and "tunc" samples now bind to server.port through this interface, and therefore work in native images without any additional reflection configuration.
