Public bug reported:

As Part of run _ensure_default_security_group is called and ends up in a
continuous loop, when detecting a Pre existing Default Security Group.

Line 549 has a continue which ends up in infinite loop, should have Max
Retries and bail out.

The Test is run with 5 workers in Neutron
