Custom media types rest (#939)

* Custom Media Types for REST

* add test, add DTO, remove example of API versioning to make example simpler

* client accept only that custom-media type

* remove not needed new_line

* leave custom media type on class level

* do not need content type header

* GET do not need content-Type

* add liveTest for custom Content type

* Merge branch 'master' of https://github.com/eugenp/tutorials into Custom_media_types_rest
