Implement IPFIX export
Define a new NXAST_SAMPLE OpenFlow vendor action and the corresponding OFPACT_SAMPLE OVS action, to do per-flow packet sampling, translated into a new SAMPLE "flow_sample" dp action. Make the userspace action's userdata size vary depending on the union member used. Add a new "flow_sample" upcall to do per-flow packet sampling. Add a new "ipfix" upcall to do per-bridge packet sampling to IPFIX collectors. Extend the OVSDB schema to support configuring IPFIX collector sets. Add support for configuring multiple IPFIX collectors for per-flow packet sampling. Add support for configuring per-bridge IPFIX sampling. Automatically generate standard IPFIX entity definitions from the IANA specs. Send one IPFIX data record message for every packet sampled by an OpenFlow sample action or received by a bridge configured with IPFIX sampling, and periodically send IPFIX template set messages.
