Record intermediate redirect locations

[marvelm]

Hi!

I've added tracking redirect locations in the response attributes. I've also pulled the status code handling logic into a separate function.

This looks good to me, but I've been on a plane for five hours and I dont understand why this isn't building the list of redirects in reverse order. It prepends, but the test shows 1, 2, 3.

I will look again when I'm less tired.

@rossabaker Nice catch! Prepending the list threw me for a spin too and I only wrote the feature a few days ago 🤦‍♂️ . I've added a comment to remind the reader that function is recursive.

[rossabaker]

Oh, right. Which works out nicely for List. Neat!

This seems binary compatible to me. We can backport this if you'd like this in the 0.18 series.

The build is failing because we need to run test:scalafmt.
