Comment 0 for bug 1638916

We were forced to use an "unsecure" in this restriction https://github.com/openstack/fuel-web/blob/master/nailgun/nailgun/fixtures/openstack.yaml#L1714, because we have bug in restriction expression parser, 'insecure' parsed as operator 'in' and 'secure' arg. We tried to fix it by changing t_IN token regexp to r'\sin\s', but it magically brakes other restriction from openstack.yaml.
