Slightly adjust responses without the need of building a response

[Kaliumhexacyanoferrat]

As a developer of a web service, I would like to change minor things of my response (such as the status code) without the need of changing my return type to IResponseBuilder so that my code stays cleaner and easier to read and maintain.

Example

[ResourceMethod(RequestMethod.PUT)]
public Result<Book> AddBook(Book book) 
{
  var entityDto = // ...;

  return new Result(entityDto, status: ResponseStatus.Created);
}

Acceptance criteria

• This new feature can used anywhere the MethodHandler is used (such as controllers or inline handlers)
• The feature has been documented on the website
• At least the following properties can be adjusted: headers, status codes
