I did this

While investigating a mailing list question I observed that CURLINFO_ACTIVESOCKET does not actually return the active socket until after the transfer is done. This appears to be due to legacy reasons, since it is a replacement for [CURLINFO_LASTSOCKET](https://curl.haxx

What we Did

Hey, this isn't a bug, it's just something me and @polarina did and we had a lot of trouble doing but in the end I believe it's worth it and worth documenting. We are open to constructive criticism for what we did. I was learning how to use proftpd as I went along so i probably made some beginner mistakes.

We created a config and systemd units for a socket activated proftpd t

aws-gate should have type annotations, so we can do more linting and discover design issues.

It would be nice to add a hostname in SSHKit's return tuple.

Currently SSHKit.run returns {:ok, output, exit_code}. https://hexdocs.pm/sshkit/SSHKit.SSH.html#run/3
This is not going to be easy to see its output without hostname when we run SSHKit.run with :parallel.

Something like {:ok, hostname, output, exit_code} will be very helpful.
