BUG/MINOR: config/server: reject QUIC addresses

QUIC is not implemented on the backend side. To prevent any issue, it is
better to reject any server configured which uses it. This is done via
_srv_parse_init() which is used both for static and dynamic servers.

This should be backported up to all stable versions.
