first draft of vnflows-monitor
Refactored the lookup methodology of the edge port db entry.
Query port_manager to see the type of a given port.
Fixed edge_to_virtual packet handling.
Temporary not handle ICMP packet instead wait until ARP cache expired.
Added new option "p 1": only show low 32bit of metadata. Made it the default.
Added decoded cookie information to output vnflows-monitor
Use openflow instead of ovs flow
Deleted unnecessary description
