Darragh O'Reilly aee87e72b1 ovs agent: signal to plugin if tunnel refresh needed 
Patch https://review.opendev.org/#/c/697655/ cannot be backported
because it includes an RPC version change. This patch is for the
stable branches.

Currently the ovs agent calls update_device_list with the
agent_restarted flag set only on the first loop iteration. Then the
server knows to send the l2pop flooding entries for the network to
the agent. But when a compute node with many instances on many
networks reboots, it takes time to readd all the active devices and
some may be readded after the first loop iteration. Then the server
can fail to send the flooding entries which means there will be no
flood_to_tuns flow and broadcasts like dhcp will fail.

This patch fixes that by also setting the agent_restarted flag if
the agent has not received the flooding entries for a network.
