Public bug reported:
In case when neutron-ovs-agent is restarted and there is rabbitmq connectivity
issue, traffic through provider networks may be broken. It is similar issue
like described in https://launchpad.net/neutron/+bug/1803919 and then it was
fixed by setting up rpc and checking if connectivity is fine before physical
bridges were configured.
But later bug https://launchpad.net/neutron/+bug/1840443 came and fix for that
https://github.com/openstack/neutron/commit/d41bd58f31e259fe408c8c059b31299fdfe81127
changed this order again. So now physical bridges are configured before rpc is
configured so it may happen again that due to broken rpc channel correct flows
will not be installed.
