Title:
  os-interface:show will not handle PortNotFoundClient exception from
  neutron

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  The os-interface:show method in the v2/v3 compute API is catching a
  NotFound(NovaException):

  http://git.openstack.org/cgit/openstack/nova/tree/nova/api/openstack/compute/contrib/attach_interfaces.py?id=2014.2.rc1#n67

  But when using the neutronv2 API, if you get a port not found it's
  going to raise up a PortNotFoundClient(NeutronClientException), which
  won't be handled by the NotFound(NovaException) in the compute API
  since it's not the same type of exception.

  http://git.openstack.org/cgit/openstack/nova/tree/nova/network/neutronv2/api.py?id=2014.2.rc1#n584

  This bug has two parts:

  1. The neutronv2 API show_port method needs to return nova exceptions,
  not neutron client exceptions.

  2. The os-interfaces:show v2/v3 APIs need to handle the exceptions
  (404 is handled, but neutron can also raise Forbidden/Unauthorized
  which the compute API isn't handling).
