#1119 - Moved WebConverters bean declaration into common HateoasConfiguration.

RestTemplateHateoasConfiguration depends on a shared bean WebConverters (previously WebMvcConverters). As it can safely be used in both WebFlux and WebMVC scenarios (as it only depends on types from spring-web), we now include a declaration in the shared HateoasConfiguration. This also allows us to remove the just introduced explicit declaration of a WebConverter bean in WebFluxHateoasConfiguration.
