class_docstr: Contains the metadata request info of a consumer.
  
  Instances of `MethodMetadataRequest` are used in this class for each
  available method under `metadatarequest.{method}`.
  
  Consumer-only classes such as simple estimators return a serialized
  version of this class as the output of `get_metadata_routing()`.
  
  .. versionadded:: 1.3
  
  Parameters
  ----------
  owner : str
      The name of the object to which these requests belong.
docstr: Prepare the given parameters to be passed to the method.
  
  The output of this method can be used directly as the input to the
  corresponding method as extra keyword arguments to pass metadata.
  
  Parameters
  ----------
  method : str
      The name of the method for which the parameters are requested and
      routed.
  
  params : dict
      A dictionary of provided metadata.
  
  Returns
  -------
  params : Bunch
      A :class:`~utils.Bunch` of {prop: value} which can be given to the
      corresponding method.
