Like for IP addresses, this patch add a new format for printfrr collection to print ISO System ID and Network address a.k.a IS-IS system ID & Network. This new format is added to the library instead of isisd because other daemons and tools need to print ISO System ID & Network Address. Signed-off-by: Olivier Dugeon <olivier.dugeon@orange.com>
