use to identify itself to Diameter peer it connects to. It is sets the
value of the Origin-Realm attribute in the Diameter messages sent to the
peer. OriginHost is not optional an must be specified in the AuthBy
DIAMETER clause. Diameter peers may use OriginHost to determine whether
they have connected to the correct peer, so it may be critical that it be
configured correctly. OriginHost defaults to the hostname of the server
Radiator is running on. Special formatting characters are supported.
Formatting is done when the configuration is loaded and AuthBy DIAMETER
clause is activated.
