commit a6b55d760bee4ea228a466cd45193f77eae53978
Author: Slawek Kaplonski <skaplons at redhat.com>

    List SG rules which belongs to tenant's SG
    
    In case when user's security group contains rules created e.g.
    by admin, and such rules has got admin's tenant as tenant_id,
    owner of security group should be able to see those rules.
    Some time ago this was addressed for request:
    
    GET /v2.0/security-groups/<sec_group_id>
    
    But it is also required to behave in same way for
    
    GET /v2.0/security-group-rules
    
    So this patch fixes this behaviour for listing of security
    group rules.
    To achieve that this patch also adds new policy rule:
    ADMIN_OWNER_OR_SG_OWNER which is similar to already existing
    ADMIN_OWNER_OR_NETWORK_OWNER used e.g. for listing or creating
    ports.

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)

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