Currently, of_core updates the flow statistics periodically based on the
settings.STATS_INTERVAL, and there is no way to notify other NApps that new statistics are available. This can cause an inconsistent view of the switch's flow table if any other NApp usesswitch.flowsafter a while since last received stats.An example of such inconsistency is the flow_manager consistency check routine, as discussed in kytos/flow_manager#124
This PR creates a new event to notify other NApps when new flow statistics are available.
Fixes #122
