@RoutingName should be applicable to method

[danielkec]

Helidon MP provides a way to define reactive routing with SE api:
https://helidon.io/docs/v2/#/mp/jaxrs/10_reactive-routing

By marking @ApplicationScoped bean which implements Service interface.

But such bean can't be created with:

    @Produces
    @ApplicationScoped
    @RoutingName("@default")
    public CoolFilteringService connectionFactory() {
        return new CoolFilteringService();
    }

As io.helidon.microprofile.server.RoutingName is not applicable on method.
