Public bug reported:

Description
===========
If Neutron disable security-group extension, Nova security group API could not handle the 404 exception which Neutron returns emitting 500 error. Security API in Nova is deprecated though I think it's better to wrap 404 exception instead of 500 error.

Steps to reproduce
==================
0) Disable neutron security-group extension
   m2_conf.ini [security_group] enabled_security_group = false
1) Request Nova to control any security-group related functions
   

Expected result
===============
Return 404 error from Nova

Actual result
=============
Return 500 error from Nova

Environment
===========
1. Exact version of OpenStack you are running. See the following
stable/ocata

2. Which hypervisor did you use?
Libvirt + KVM

2. Which storage type did you use?
Ceph

3. Which networking type did you use?
Neutron with linuxbridge
