feat(client): add a new Client struct with super powers

- Includes ergonomic traits like IntoUrl and IntoBody, allowing easy
usage.
- Client can have a RedirectPolicy.
- Client can have a SslVerifier.

Updated benchmarks for client. (Disabled rust-http client bench since it
hangs.)

 //! HTTP Client
+//!
+//! # Usage
+//!
+//! The `Client` API is designed for most people to make HTTP requests.
+//! It utilizes the lower level `Request` API.
+//!
+//! ```no_run
+//! use hyper::Client;
+//!
+//! let mut client = Client::new();
+//!
+//! let mut res = client.get("http://example.domain").send().unwrap();
+//! assert_eq!(res.status, hyper::Ok);
+//! ```
+//!
+//! The returned value from is a `Response`, which provides easy access
+//! to the `status`, the `headers`, and the response body via the `Writer`
+//! trait.
