Variables

var Closure = func() func() {
	retryIn := 0
	fibonacci := Fibonacci()
	return func() {
		if retryIn > 0 {
			durationString := fmt.Sprintf("%vs", retryIn)
			duration, _ := time.ParseDuration(durationString)

			log.WARNING.Printf("Retrying in %v seconds", retryIn)
			time.Sleep(duration)
		}
		retryIn = fibonacci()
	}
}

Closure - a useful closure we can use when there is a problem connecting to the broker. It uses Fibonacci sequence to space out retry attempts
