[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

- Ensure response IDs are unique, even if the first sentence is identical
- Handle responses where different responses produce a different type of data
- Use the correct mime type for plain text and byte streams
- Tidy up whitespace in client-mod.mustache
- Specify locale for String.format
- Add test for multiple response types
- Update samples

Based on this [issue](https://github.com/servo/rust-url/issues/416) the `utf8_percent_encode` doesn't percent encode `+` instead treats it as a space which is may cause a problem if the query parameters contain one. For example if we wanted to use a DateTime range in query parameters:
`{base_path}{path}?start=2019-02-12T00:00:00+00:00&end=2019-02-13T15:00:00+00:00`
These parameters may be decoded as:
```
start = 2019-02-12T00:00:00 00:00
end = 2019-02-13T15:00:00 00:00
```
To solve this I changed query parameters to be form-urlencoded using `url::form_urlencoded` based on what's done in [`rust` client generator](ea08106c80/modules/openapi-generator/src/main/resources/rust/request.rs (L106)).
