ipfix: add classification nodes for flow statistics (VPP-204)
In order to have meaningfull IPFIX implementation we should be able to classify all packets flowing through vpp. But existing IPv4 and IPv6 classifier nodes are called only if destination IP address is local to vpp. This commit adds new IPv4 and IPv6 classifier nodes that should be used for collecting flow statistics.
