tlshd: use quic_config to get parameters for quic handshake

The latest update to the QUIC module has moved several parameters from
quic_transport_param to quic_config. These include important handshake-
related parameters such as receive_session_ticket, certificate_request,
and payload_cipher_type.

So rename quic_conn_get_transport_param() to quic_conn_get_config(), and
Use the QUIC_SOCKOPT_CONFIG socket option to retrieve these parameters
before initiating the QUIC handshake.
