Title:
  FIP isn't properly created for octavia loadbalancers

Status in neutron:
  Invalid

Bug description:
  After upgrading from an earlier version of stable/stein to a newer
  version (released around 2020-02-20) , FIP's on newly created octavia
  loadbalancers stopped working.

  So what we can see is that everything works except the snat namespaces
  never gets the ip assigned via rootwrap nor the iptables rules. It
  never happens and there are no errors around this.

  Any old loadbalancers that exist work, but can't create new ones.
  The loadbalancers themselves work great, using shared networks or tenant networks they work great too. Asked about it in the octavia irc but they pointed me to neutron.

  Instances can be assigned FIP's normally without issues.

  I could use some help/pointers on where to troubleshoot this.
  Debug is enabled on neutron but there are simply no errors, everything just seems to be fine with whats happening.

  I'm using DVR HA with OVS.

  I'm not even sure what logs to attach since nothing is complaining or
  spitting out any errors.
