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().
