*  **TunnelRequest is gone.** It specified how to connect to an HTTP proxy.
    OkHttp 2 uses the new `Request` class for this.

 *  **Dispatcher** is a new class that manages the queue of asynchronous calls. It
    implements limits on total in-flight calls and in-flight calls per host.

#### Implementation changes

 * Support Android `TrafficStats` socket tagging.
 * Drop authentication headers on redirect.

 *  **Interceptors are more capable.** The `Chain` interface now offers access
    to the call and can adjust all call timeouts. Note that this change is
    source-incompatible for code that implements the `Chain` interface.
    We don't expect this to be a problem in practice!

 *  **OkHttp has an experimental new API for tracking metrics.** The new
