    Add list security group rules API test
    
    This test checks that regular user can see all SG rules which belongs
    to his tenant OR belongs to security group owned by his tenant.
    
    This test also ensures that SG rules from different tenants and Security
    Groups are not visible for regular user.

Title:
  Security Group filtering hides rules from user

Status in neutron:
  Fix Released
Status in OpenStack Security Advisory:
  Won't Fix

Bug description:
  Manage Rules part of the GUI hides the rules currently visible in the
  Launch Instance modal window.

  It allows a malicious admin to add backdoor access rules that might be
  later added to VMs without the knowledge of owner of those VMs.

  When sending GET request as below, it responds only with the rules
  that are created by user and this happens when using Manage Rules part
  of the GUI: <WSGIRequest: GET
  '/project/security_groups/3a833936-f485-4a37-bb5b-d4694c7e18eb/'>

  On the other hand when using GET request as below, it responds with
  all SG and it includes all rules, and there is no filtering and this
  is used in Launch Instance modal window: <WSGIRequest: GET
  '/api/network/securitygroups/'>

  Here is example of rules display in Manage Rules part of GUI:

  > /opt/stack/horizon/openstack_dashboard/dashboards/project/security_groups/views.py(50)_get_data()
  -> return api.neutron.security_group_get(self.request, sg_id)

  As you might have noticed there are no ports access 44 and 22 (SSH)

  And from the Launch Instance Modal Window, as well as CLI we can see
