Title:
  vif_port_id of ironic port is not updated after neutron port-delete

Status in OpenStack Compute (nova):
  Expired

Bug description:
  Steps to reproduce
  ==================
  1. Get list of attached ports of instance:
  nova interface-list 42dd8b8b-b2bc-420e-96b6-958e9295b2d4
  +------------+--------------------------------------+--------------------------------------+-----------------------------------------------+-------------------+
  | Port State | Port ID | Net ID | IP addresses | MAC Addr |
  +------------+--------------------------------------+--------------------------------------+-----------------------------------------------+-------------------+
  | ACTIVE | 512e6c8e-3829-4bbd-8731-c03e5d7f7639 | ccd0fd43-9cc3-4544-b17c-dfacd8fa4d14 | 10.1.0.6,fdea:fd32:11ff:0:f816:3eff:fed1:8a7c | 52:54:00:85:19:89 |
  +------------+--------------------------------------+--------------------------------------+-----------------------------------------------+-------------------+
  2. Show ironic port. it has vif_port_id in extra with id of neutron port:
  ironic port-show 735fcaf5-145d-4125-8701-365c58c6b796
  +-----------------------+-----------------------------------------------------------+
  | Property | Value |
  +-----------------------+-----------------------------------------------------------+
  | address | 52:54:00:85:19:89 |
  | created_at | 2016-07-20T13:15:23+00:00 |
  | extra | {u'vif_port_id': u'512e6c8e-3829-4bbd-8731-c03e5d7f7639'} |
  | local_link_connection | |
  | node_uuid | 679fa8a9-066e-4166-ac1e-6e77af83e741 |
  | pxe_enabled | |
  | updated_at | 2016-07-22T13:31:29+00:00 |
  | uuid | 735fcaf5-145d-4125-8701-365c58c6b796 |
  +-----------------------+-----------------------------------------------------------+
  3. Delete neutron port:
  neutron port-delete 512e6c8e-3829-4bbd-8731-c03e5d7f7639
  Deleted port: 512e6c8e-3829-4bbd-8731-c03e5d7f7639
  4. It is gone from interface list:
  nova interface-list 42dd8b8b-b2bc-420e-96b6-958e9295b2d4
  +------------+---------+--------+--------------+----------+
  | Port State | Port ID | Net ID | IP addresses | MAC Addr |
  +------------+---------+--------+--------------+----------+
  +------------+---------+--------+--------------+----------+
  5. ironic port still has vif_port_id with neutron's port id:
  ironic port-show 735fcaf5-145d-4125-8701-365c58c6b796
  +-----------------------+-----------------------------------------------------------+
  | Property | Value |
  +-----------------------+-----------------------------------------------------------+
  | address | 52:54:00:85:19:89 |
  | created_at | 2016-07-20T13:15:23+00:00 |
  | extra | {u'vif_port_id': u'512e6c8e-3829-4bbd-8731-c03e5d7f7639'} |
  | local_link_connection | |
  | node_uuid | 679fa8a9-066e-4166-ac1e-6e77af83e741 |
  | pxe_enabled | |
  | updated_at | 2016-07-22T13:31:29+00:00 |
  | uuid | 735fcaf5-145d-4125-8701-365c58c6b796 |
  +-----------------------+-----------------------------------------------------------+

  Expected result
  ===============
  ironic port should not have vif_port_id in extra field.

  Actual result
  =============
  ironic port has vif_port_id with id of deleted neutron port.

  This can confuse when user wants to get list of unused ports of ironic node.
  vif_port_id should be removed after neutron port-delete.
