In virtual network, users want more info about the virtual point to observe the traffic.
It should be a string to provide clear info, not a simple interger ID.
Introduce "other-config: virtual_obs_id" in IPFIX, which is a string configured by user.
Introduce an enterprise IPFIX entity "virtualObsID"(898) to export the value. The entity is a
variable-length string.

Extend IPFIX exporter to export tunnel headers when both input and output
of the port.
Add three other_config options in IPFIX table: enable-input-sampling,
enable-output-sampling and enable-tunnel-sampling, to control whether
sampling tunnel info, on which direction (input or output).
Insert sampling action before output action and the output tunnel port
is sent to datapath in the sampling action.
Make datapath collect output tunnel info and send it back to userpace
in upcall message with a new additional optional attribute.
Add a tunnel ports map to make the tunnel port lookup faster in sampling
upcalls in IPFIX exporter. Make the IPFIX exporter generate IPFIX template
sets with enterprise elements for the tunnel info, save the tunnel info
in IPFIX cache entries, and send IPFIX DATA with tunnel info.
Add flowDirection element in IPFIX templates.
