AssertionError: list of iptables rules are not equal

Alwo we do not need execute this tests 2 times(in ubuntu thread and centos) according to it related for master node only

Reproduce case manually:
The list of iptables rules is different before backup,restore and after, see the attach.

This is a duplicate of 1362159. Despite our best efforts, it's difficult to get all the iptables rules to match correctly. The issues are related to rules created by docker, not by dockerctl. The rules in question will not be an issue if we switch to host networking in a newer version of docker, which is planned for 6.0.
