Add unit test for NoBackoff

We don't need to sleep and calculate to variable here.
Just keep it running without waiting.
So finally, the expected duration will be smaller than 100 milliseconds

func TestNoBackoff(t *testing.T) {
	var counting int64

	start := time.Now()
	goretry.NoBackoff(func() error {
		counting++
		if counting > 5 {
			return nil
		}
		return errors.New("fake error")
	})

	duration := time.Since(start)

	expectedCounting := int64(6)
	if counting != expectedCounting {
		t.Errorf("NoBackoff() expected counting: %d, actual: %d", expectedCounting, counting)
	}

	expectedDuration := 100 * time.Millisecond
	if duration > expectedDuration {
		t.Errorf("NoBackoff() expected duration: %d, actual: %d", expectedDuration, duration)
	}
}

Do you mean that it would be like this? If yes, may I ask why it is 100 * time.Millisecond as I don't see the relevance between it and action function? Or is it just a magic number?

it's just a magic number that we do 6 actions without any sleeping can't reach to
