[Rust Server] Fix panic handling headers (#4877)
[Rust Server] Fix panic handling headers

If we have an API which has multiple auth types, we may panic. This is because
in Hyper 0.11, the following code will panic:

```
use hyper::header::{Authorization, Basic, Bearer, Headers};
fn main() {
    let mut headers = Headers::default();
    let basic = Basic { username: "richard".to_string(), password: None };
    headers.set::<Authorization<Basic>>(Authorization(basic));
    println!("Auth: {:?}", headers.get::<Authorization<Bearer>>());
}
```

as it mixes up an `Authorization<Basic>` and `Authorization<Bearer>` as both
have `Authorization:` as the header name.

This is fixed by using `swagger::SafeHeaders` added in
