QUIC: application init() callback. It's called after handshake completion or prior to the first early data stream creation. The callback should initialize application-level data before creating streams. HTTP/3 callback implementation sets keepalive timer and sends SETTINGS. Also, this allows to limit max handshake time in ngx_http_v3_init_stream().
