Use new configuration infrastructure on MappingJackson2MessageConverter / Jackson2CodecSupport #1453
Description
The current converter and and codec arrangement leaves Spring HATEOAS subject to invalid response type selection in certain configuration and request scenarios (see spring-projects/spring-framework#26212 for details). Spring Framework 5.3.4 introduces advanced configuration APIs on MappingJackson2MessageConverter and its reactive sibling. We should move to that to avoid the problem described in the linked ticket.
