Title:
  500 error and 2 traces if no free fixed IP left in the neutron network

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  If nova recieve 404 from neutron due lack of free fixed IPs, it traces
  badly and return 500 error to user.

  Steps to reproduce:
  0. Setup nova & neutron, create network & subnetwork
  1. Consume all IP from that network
  2. Try to attach interface to that network (nova interface-attach --net-id NET-UUID SERVER-UUID)

  Actual behaviour:

  ERROR (ClientException): The server has either erred or is incapable
  of performing the requested operation. (HTTP 500) (Request-ID: req-
  994444ec-6a69-428d-9c16-c58d685553dd)

  ... and traces (see below)

  Expected behaviour:

  Proper complain about lack of IP (NoMoreFixedIps) and proper HTTP
  error code.

  Traces (nova-api):
