HTTP/2: server push.
Resources to be pushed are configured with the "http2_push" directive.
Also, preload links from the Link response headers, as described in
https://www.w3.org/TR/preload/#server-push-http-2, can be pushed, if
enabled with the "http2_push_preload" directive.
Only relative URIs with absolute paths can be pushed.
The number of concurrent pushes is normally limited by a client, but
cannot exceed a hard limit set by the "http2_max_concurrent_pushes"
directive.
