chore: add FromStr for Endpoint

[Hoverbear]

Motivation

This is particularly handy when combined with clap::value_t.

Here's demo of it working with Clap:

cargo +stable init --bin tonic-demo
cd tonic-demo
cat <<-EOF >> Cargo.toml
  clap = "*"
  tonic = { path = "../hyperium/tonic/tonic" }
EOF
cat <<-EOF > src/main.rs
    use clap::{value_t, App, Arg};
    use tonic::transport::Endpoint;
    fn main() {
        let matches = App::new("tonic-demo")
            .arg(Arg::with_name("host"))
            .get_matches();
        let x = value_t!(matches.value_of("host"), Endpoint);
        println!("{:?}", x);
    }
EOF
cargo +stable run -- https://127.0.0.1:443

Solution

Add a impl FromStr for Endpoint. It clones since the s's lifetime is too short otherwise.

I'm sorry -- I don't really know how to reconcile this.

Can you provide guidance?

@Hoverbear that was a very helpful error message from gh lol. Restarted the checks, lets see if it works this time...
