 * Manages Page networking layer.

 * This class exposes useful network-related functionality such as:
 *
 *   - waiting for "network silence" (i.e. no new requests fired for specified duration)
 *   - accessing request/response information on current target (since last page load event,
 *     similar to DevTools)
 *   - obtaining request/response body of selected requests (with same limitations as in DevTools)
