docs: A helper to retrieve an integer value from a given dictionary
      containing string values.  If the requested value is not present
      in the dictionary, or if it cannot be converted to an integer, a
      default value will be returned instead.
  
      :param config: The dictionary containing the desired value.
      :param key: The dictionary key for the desired value.
      :param default: The default value to return, if the key isn't set
                      in the dictionary, or if the value set isn't a
                      legal integer value.
  
      :returns: The desired integer value.
