`CDNOriginHost` is the domain name of the _origin_ server (i.e. the server running Cloak) under `CDN` mode. This only
has effect when `Transport` is set to `CDN`. If unset, it will default to the remote hostname supplied via the
commandline argument (in standalone mode), or by Shadowsocks (in plugin mode). After a TLS session is established with
the CDN server, this domain name will be used in the HTTP request to ask the CDN server to establish a WebSocket
connection with this host.
