Description
Derived from CONFDEV-24631 and some PR comments, not all Maps should be converted to EnrichableMap when deserialized from JSON.
Opting in can be done with the @JsonDeserialize(as=EnrichableMap.class) annotation, but there's a catch.
A spike of implementing this shows that it breaks Content+Space roundtrip unit tests that can't get the EnrichedMapDeserializer from the SerializerModule because it's in conf-rest-serialization module while the unit tests are in conf-java-api.
If we move all of the roundtrip tests to the rest module, we should be able to keep the java-api test code very lean.
