WaitAndRetry about retry-go

Hi @jurabek the idea of your snippet is first to try delay is 1s, second 2s, third 3s, and next one 3s too? I think this is possible to do by custom DelayFunction. I maybe add some examples of how to make custom DelayFunctions to README or examples.

Great I have it in examples
https://github.com/avast/retry-go/blob/master/examples/custom_retry_function_test.go

in your case can be easily solved by something like:

retry.DelayType(func(n uint, config *retry.Config) time.Duration {
                        switch n {
                        case 1:
                            return 1
                        case 2:
                            return 2
                        default:
                            return 3
                        }
		}),

Hi @JaSei, yes this one was exactly what I need, thank you for the example.
