Generated Enum DTOs

[nirodg]

The generated DTO uses the original ENUM that is defined in the Entity. We need to make sure we have a 1:1 unless specified by the user, possibly supplying CUSTOM_DTO_ENUM.class to the HyperResource

Current generated code:

@JsonInclude(JsonInclude.Include.NON_NULL)
public class OrderDTO extends HyperDto {
    @JsonProperty("orderNumber")
    private int orderNumber;

    @JsonProperty("status")
    private OrderStatus status; // <-- Not the expected behavior 
...

Expected:

   @JsonProperty("status")
    private OrderStatusDTO status; // <-- Expected DTO
