on RHEL-9 there is no iptables package, we need to install
iptables-nft package here.
In CentOS Stream-9 and Fedora-34 onwards iptables-nft package
is available.[1]
But we also need to support other distros, so we are introducing
iptables_packages var and distro specific var files (having different
name) for installing iptables package.

This adds nodes in a multi-node job to each other's firewalls so that
they can communicate with each other without restrictions.
