Merge #30: Derive Clone and implement {url, client} for AsyncClient

5553784 Add `BlockingClient::{url, agent}` (Hirrolot)
80f648b Derive `Clone` and implement `{url, client}` for `AsyncClient` (Hirrolot)

Pull request description:

  Summary:
   - `#[derive(Clone)]` for `AsyncClient` so that it can now be cloned. The implementation should be cheap because `reqwest::Client` is wrapped in `Arc` automatically, and the `url` field should not be large either.
   - Add the `{url, client}` getters. They are helpful when you want to obtain data from which `AsyncClient` was constructed and don't want to pass these parameters around your code.
