* @summary This test verifies that if an h2 connection going through a
*          proxy P is downgraded to HTTP/1.1, then a new h2 request
*          going to a different host through the same proxy will not
*          be preemptively downgraded. That, is the stack should attempt
*          a new h2 connection to the new host. It also verifies that
*          the stack sends the appropriate "host" header to the proxy.
