hyper-util Client examples are wrong

[frederikhors]

All (or many) examples in this page are wrong, at least I think: https://docs.rs/hyper-util/latest/hyper_util/client/legacy/struct.Client.html.

E.g.:

let client = Client::new();

new() doesn't exist anymore (and I don't know what to use).

The docs should be fixed by hyperium/hyper-util#65, but the changes haven't been reflected yet.

Basically, you need to do something like:

let client: Client<_, Full<Bytes>> = Client::builder(TokioExecutor::new()).build_http();
