Update parameter labels for GRPCClient

Motivation:

The updated generated code added parameter labels to the handler passed
to each method of the GRPCClient. This was done purposefully to improve
readability. We haven't as yet actually updated the client to use the
new labels.

Modifications:

- Update param labels in GRPCClient

Result:

New generated code compiles
