Title:
  Nova API floating IP error code inconsistent between Nova-Net and
  Quantum

Status in OpenStack Compute (Nova):
  Fix Released
Status in Tempest:
  Confirmed

Bug description:
  If you ask for details of a floating IP address (GET    .../os-
  floating-ips/<id>)   that is not allocated to you, then on a system
  with Nova-networking the error code is 404 itemNotFound,  whereas on a
  system with Quantum the error code is 500 computeFault.

  
  The Nova Floating IP API code (api/openstack/compute/contrib/floating_ips.py)  traps the NotFound exception raised by Nova-Net, but the quantum networking raises a QuantumClientException.

  Not clear to me if the network/quantumv2/api code can just trap that
  exception in this case and translate it to NotFound. or if we need a
  seperate exception from the quantum client
