Let's Encrypt integration

[jwdeitch]

the lets-encrypt branch contains the effort to automatically handle authorization and certificate signing via Let's Encrypt. A background worker thread can be spun for auto-renewal with the intention of checking the expiration status once per week. It should be possible to rotate the certs without dropping requests by possibly queuing them when the renewal is triggered(?)

This is so cool, I was thinking on doing something for authorization. Let me know How I can give you a hand.

@jwdeitch please let me know how I can contact you so you can explain me your idea a little better and see how I can help you better. I'm on gitter.im/actix/actix leave me a message

[neoeinstein]

I'd like to follow this as well. Ping me on a PR when you have one ready to work through.

Did this not progress any further?

Nothing built in or bespoke for Actix Web (yet), but this example using acme-micro solves the problem, I believe.
