atomic: add comment on why we disable firewall
In cloud Images we do this becaue it's generally accepted that
in a cloud environment there are higher level firewall constructs
(i.e. security groups).

# Fedora Atomic Host is the Fedora version of the "Atomic Host" pattern
# from [Project Atomic](http://www.projectatomic.io/).
# This kickstart is used for cloud/virt images, and uses cloud-init
# to bootstrap authentication, just like Fedora Cloud Base. (Also note the
# fedora-atomic-vagrant.ks kickstart inherits from this).
# One very important thing to understand is that this image contains the same
# OSTree commit as will be used on bare metal installations - Fedora Atomic Host
# also has an ISO. One difference though is that cloud-init isn't enabled for
# bare metal. When processing this kickstart then, Anaconda isn't actually
# installing packages - it's just replicating a "pre-assembled" tree from
# rpm-ostree.
# Basically, the `ostreesetup` verb replaces the traditional `%packages`
# section. For example, `rpm-ostree status` can show you the same checksum and
# version from an ISO install and this cloud image - it's the same bits.
