This is in service to gRFC A89. Since the gRFC isn't finalized this purposefully doesn't really do anything yet. The grpc-opentelemetry change to use this optional label will be done after the gRFC is merged. grpc-opentelemetry currently has a hard-coded list (one entry) of labels that it looks for, and this label will need to be added.
