HTTP/2 server support

[fluffysquirrels]

I'm looking to serve HTTP/1.1 and HTTP/2 over TLS behind the same port with ALPN. Is that within scope for this crate or as an example in this crate?

Yes! In this example, hyper will automatically use HTTP/2 if a client starts talking HTTP/2, otherwise HTTP/1.1 will be used.

That's a great feature.

I created a PR to mention HTTP/2 support in the comment block in the example.

I don't think HTTP/2 works in the server example currently based on local testing with curl. I pushed a PR (#91) to configure ALPN, which fixes this.

My PRs got merged so I'll close this now.
