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.
