QUIC: simplified configuration.

Directives that set transport parameters are removed from the configuration.
Corresponding values are derived from the quic configuration or initialized
to default.  Whenever possible, quic configuration parameters are taken from
higher-level protocol settings, i.e. HTTP/3.

Along with "http3" or "quic", you also have to specify "reuseport"
option [6] to make it work properly with multiple workers.
A number of directives were added that specify transport parameter values:
quic_max_idle_timeout
quic_max_ack_delay
quic_max_udp_payload_size
quic_initial_max_data
quic_initial_max_stream_data_bidi_local
quic_initial_max_stream_data_bidi_remote
quic_initial_max_stream_data_uni
quic_initial_max_streams_bidi
quic_initial_max_streams_uni
quic_ack_delay_exponent
quic_disable_active_migration
quic_active_connection_id_limit
To enable address validation:
quic_retry on;

quic_gso on;
To limit maximum packet size:
quic_mtu <size>;
To set host key for various tokens:
quic_host_key <filename>;
By default this Linux-specific optimization [8] is disabled.
Enable if your network interface is configured to support GSO.
A number of directives were added that configure HTTP/3:
http3_max_table_capacity
http3_max_blocked_streams
http3_stream_buffer_size
http3_max_concurrent_pushes
http3_max_concurrent_streams
http3_push
http3_push_preload
