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.
