class_docstr: An RpcController mediates a single method call.
  
  The primary purpose of the controller is to provide a way to manipulate
  settings specific to the RPC implementation and to find out about RPC-level
  errors. The methods provided by the RpcController interface are intended
  to be a "least common denominator" set of features which we expect all
  implementations to support.  Specific implementations may provide more
  advanced features (e.g. deadline propagation).

docstr: Checks if the client cancelled the RPC.
  
  If true, indicates that the client canceled the RPC, so the server may
  as well give up on replying to it.  The server should still call the
  final "done" callback.
