We add the possibility to set and get a 128 bit node identifier, as an alternative to the legacy 32-bit node address we are using now. We also add an option to set and get 'clusterid' in the node. This is the same as what we have so far called 'netid' and performs the same operations. For compatibility the old 'netid' commands are retained, -we just remove them from the help texts.
