Title:
  IP filtering can include duplicate instances

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  The IP address filtering logic implemented in the compute API can duplicate instances if a given instance either:
  - Has a fixed IP address in more then 1 network that matches the filter
  - Has more then 1 fixed IP address in the same network matches the filter

  For example:

  $ nova list
  +-----+-----------------+-------------------------------------------------+
  | ID  | Name            | Networks                                        |
  +-----+-----------------+-------------------------------------------------+
  | 123 | InstanceTest    | gre_shared_1=192.168.0.11; network=194.168.0.14 |
  | 456 | InstanceOne     | gre_shared_1=192.168.0.3                        |
  +-----+-----------------+-------------------------------------------------+

  $ nova list --ip 19
  +-----+-----------------+-------------------------------------------------+
  | ID  | Name            | Networks                                        |
  +-----+-----------------+-------------------------------------------------+
  | 123 | InstanceTest    | gre_shared_1=192.168.0.11; network=194.168.0.14 |
  | 123 | InstanceTest    | gre_shared_1=192.168.0.11; network=194.168.0.14 |
  | 456 | InstanceOne     | gre_shared_1=192.168.0.3                        |
