docs: Get assignment by name.
  
          Get an assignment by name. It works by retrieving all assignments
          and returning the first assignment with a matching name. If the
          optional parameter ``assignments`` is provided, it uses this
          collection rather than retrieving all assignments from the service.
  
          Args:
              assignment_name (str): name of assignment
              assignments (list): assignments to search, default: None
                  When ``assignments`` is unspecified, all assignments
                  are retrieved from the service.
  
          Raises:
              requests.RequestException: Exception connection error
              ValueError: Unable to decode response content
  
          Returns:
              tuple: tuple of assignment id and assignment dictionary
