func (nr *NATSRequest) Response() *Msg {
	m := nr.c.GetMsg()
	m.AssertSubject(nr.inb)
	return m
}
Response gets the next pending message that is published to NATS by the
service.

If no message is received within a set amount of time, or if the message is
not a response to the request, it will log it as a fatal error.
