[RADIATOR] Formatting character for next hop servers when proxying

[Heikki Vatiainen]

Does anyone know how to get the IPv4 or IPv6 address of the next hop a
request was forwarded to? This is when proxying RADIUS requests.

The manual has %c and %C that are the IP address or DNS name of the
sender, but I could not find a formatting character for the next hop proxy.

AuthBy DNSROAM, RADIUS, SQLRADIUS and LDAPRADIUS at least are the ones
where the next hop RADIUS is resolved during the runtime. For logging
purposes it might be useful to know which IP address was the destination
that was chosen.

Thanks!
