Title:
  [RFE] No notification on floating ip status change

Status in neutron:
  Triaged
Status in OpenStack Search (Searchlight):
  New

Bug description:
  Tested on neutron/master in devstack.

  When I associate or disassociate a floating IP I get a notification
  indicating the new fixed IP and port association, but the status still
  indicates the current value (so for associate, the notification
  contains "fixed_ip_address":"a.b.c.d", "status": "DOWN") because
  there's a short latency time before the FIP is marked as ACTIVE.

  I see the status change after a very short period after in the q-svc
  log:

      New status for floating IP 8470e622-0f3b-419f-ac21-deed658d3260:
  ACTIVE

  There's no notification emitted representing this state change,
  however. The same is true on disassociate; the port and fixed IP are
  cleared but the status is indicated ACTIVE and there's no notification
  marking it DOWN.

  E.g.
  $ neutron floatingip-create 0e97853d-3ac0-4c08-a8b3-f6bfa443dd24
