    Remove Floating IP DNS record upon associated port deletion
    
    Port deletion triggers disassociate_floatingips. This patch ensures
    that method not only clears the port association for a Floating IP,
    but also removes any DNS record associated with it.

Title:
  Neutron doesn't delete Designate entry when port is deleted

Status in neutron:
  Fix Released

Bug description:
  When a port with a FIP and DNS association is deleted, Neutron
  integration is not deleting the DNS entry from Designate.

  To reproduce use the following flow:

  # Create a Designate zone and associate with a tenant network
  openstack zone create --email admin@xxxxxxxxxxx example.org.
  neutron net-create net1 --dns-domain example.org.
  neutron subnet-create --name sub1 net1 192.168.1.0/24

  # Create a router, and attach tenant network to a public network
  neutron router-create rtr
  neutron router-interface-add rtr sub1
  neutron router-interface-add rtr sub2
  neutron router-gateway-set rtr public

  # Create a port, associate with a FIP
  PORT_ID=$(neutron port-create --name testport --dns-name testport net1 | awk '/ id /{print $4}')
  neutron floatingip-create --port-id $PORT_ID public

  # Entry should be seen in Designate recordset
  openstack recordset list example.org.

  # Delete port
  neutron port-delete $PORT_ID

  # Entry is expected to be deleted from Designate recordset. Yet it isn't
  openstack recordset list example.org.
