Hello,

I'm using ovs agents with L2 population mechanism in ML2 plugin. I noticed 
that sometimes agents don't receive proper RPC to add new vxlan tunnel 
openflow rules and then vxlan network between some compute nodes not working.
I'm now using still havana release but want to upgrade to Juno. I was checking 
Juno code in l2 population mech driver and ovs plugin and I didn't find 
anything like periodic check if openflow rules are proper set or maybe 
resynced. 
Maybe it would be also good idea to add something like that to ovs agent?
