OFAgent: Flow-based tunneling

Registered by YAMAMOTO Takashi on 2014-10-15

use flow-based tunneling, using tun_ipv4_src/tun_ipv4_dst NXMs.

Note: while the use of NXMs contradicts to the one of goals of
ofagent, i.e. being portable to other switch implementations,
it isn't a problem right now because:

- the tunneling support is OVS-dependent anyway

- i've heard that the future versions of OpenFlow aims to the same direction

Whiteboard

February-3 (mestery): Moving to Kilo-3. After discussions with armax, it's unclear whether this should be allowed into the in-tree plugin given the plugin decomposition work going on with ofagent now. We'll discuss this after Kilo-2 is complete.

December-5 (mestery): Kilo-2, please free to target to Kilo-1 if you think you can squeeze this in there.
