Request for example using hyper directly with tonic

[sammyne]

We now have examples of using hyper directly with tonic, so for now you can use hyper-tls or hyper-openssl to achieve what you want.

Hey, would you mind posting the link to examples of using hyper-tls/hyper-openssl directly with tonic, please~

I don't have one handy at the moment, but would be good to add one. I am hesitant to including one in the examples folder since I don't want to have to compile openssl just to compile tonic.
