docs: This operation returns the list of domain-specific models that are supported by the Computer Vision API.  Currently, the API only supports one domain-specific model: a celebrity recognizer. A successful response will be returned in JSON.  If the request failed, the response will contain an error code and a message to help understand what went wrong.
  
  @param serviceCallback the async ServiceCallback to handle successful and failed responses.
  @throws IllegalArgumentException thrown if parameters fail the validation
  @return the {@link ServiceFuture} object
