LIU Yulong 9583dc0549 More accurate agent restart state transfer 
Ovs-agent can be very time-consuming in handling a large number
of ports. At this point, the ovs-agent status report may have
exceeded the set timeout value. Some flows updating operations
will not be triggerred. This results in flows loss during agent
restart, especially for hosts to hosts of vxlan tunnel flow.

This fix will let the ovs-agent explicitly, in the first rpc loop,
indicate that the status is restarted. Then l2pop will be required
to update fdb entries.
