Title:
  Openvswitch ports not getting recreated

Status in neutron:
  Won't Fix

Bug description:
  Due to an apparent communication issue between neutron-openvswitch-
  agent and openvswitch  we were in a situation where we had linux veth
  devices set up for a given instance (eg. tapXXX, qvbXXX) but were
  missing corresponding ovs ports and iptables rules.

  In this situation we had to manually delete veth devices and restart
  nova-compute and neutron-openvswitch-agent to get openvswitch ports
  and iptables rules recreated.

  It would be more robust if neutron and openvswitch would automatically
  detect missing objects and synchronize their view of which devices and
  ports should be present

  Versions: 
  Openstack Mitaka on Ubuntu xenial
  neutron: 2:8.4.0-0ubuntu5  
  openvswitch-switch 2.5.2-0ubuntu0.16.04.1
