Upgrades, dockerctl errors in logs during the upgrade

[Evgeniy L]

1. install 5.0 iso
2. run upgrade to 5.1

Actual result:
It happens all the time.
Upgrade succeed, but there are a lot of dockerctl errors in upgrade logs which can confuse the user.

Expected result:
Upgrade succeed and there is no dockerctl errors in logs

    Upgrades, run iptables cleaning only for required containers

    I doesn't make sence to run iptables
    cleaning, for containers, which
    doesn't have port bindings, e.g.
    volume containers.
