Public bug reported:

[Impact]

The fix for the following bug was found to cause a regression/race with
neutron-ovs-cleanup and neutron-openvswitch-agent where ports/flows get
deleted and do not get restored.

https://bugs.launchpad.net/ubuntu/+source/neutron/+bug/1752838

[Test Case]
* Deploy OpenStack Mitaka with one compute, one gateway and gre overlay
* Create instance on gre overlay network
* Add FIP to instance
* Start a ping to FIP
* juju ssh nova-compute/0
* Check 'ovs-ofctl dump-flows br-tun' and observe table=20 egress flows for qdhcp and qrouter
* systemctl restart openvswitch-switch
* Check that flows re-added to br-tun
* Check that ping still running

[Regression Potential]

There should be none as long as the code is reverted to what it was
before the SRU for 1752838.
