Public bug reported:
In fullstack tests there is many times error with creating e.g. "host-xxxx"
namespace. Error message tells that such namespace already exists and test is
failing because of that.
It looks that this is kind of race condition when ip.netns.exists() method
return false but few miliseconds later namespace already exists and
ip.netns.add() method fails.
It is in method ensure_namespace() in
https://github.com/openstack/neutron/blob/master/neutron/agent/linux/ip_lib.py#L204
** Affects: neutron
