Getting the retry attempt number in the body of retry about elixirretry

Off the top of my head, doing so would be a bit tricky. Out of curiosity, why do you need to increase the timeout?

Hi,

during the initialization of our Elixir service, we need to consume from another backend service using HTTP. Certain requests are slow no matter on the load (> x3 the averge). For such cases, we would like to have a way to increase the timeout threshold in HTTPotion, otherwise they will never be able to succeed.

OK.

At any rate, it's a cool feature to have. I don't know if I can commit to it in the near future, but I welcome a PR.
