Comment 55 for bug 1687027

Even with added recently skip_if_timeout decorator those tests are failing from time to time and it looks that it may happen that different type of exception is raised in such case.
For example: http://logs.openstack.org/73/636473/25/check/neutron-functional-python27/0ef9362/testr_results.html.gz

We will have to handle more exception types in this decorator.
