NS8 Change node SSH port 22 permanently

Feature
15

This is a shorter alternative procedure based on firewall-cmd only:

firewall-cmd --permanent --add-forward-port=port=2222:proto=tcp:toport=22
firewall-cmd --permanent --service=ssh --add-port=2222/tcp
firewall-cmd --permanent --service=ssh --remove-port=22/tcp
firewall-cmd --reload

Check the configuration with

firewall-cmd --list-all

I didn’t test it, but It should work on Debian, too.
