Support unix sockets (hackney 1.6.2)

[rhruiz]

Hello,

hackney recently introduced support for making requests on unix sockets using the scheme http+unix://. The following code on base.ex prepends an extra http:// on the url breaking the request:

@doc false
def default_process_url(url) do
  case url |> String.slice(0, 8) |> String.downcase do
    "http://" <> _ -> url
    "https://" <> _ -> url
    _ -> "http://" <> url
  end
end

As a workaround, I can implement my own module with the HTTPoison.Base macro and override process_url.

Can we get that allowed on the default_process_url as well?

Thanks!

Definitely! Do you mind sending a PR for this change?

Sure thing, just had to add unix sockets to httparrot to write the tests: edgurgel/httparrot#23

I will send the PR next
