Change customizations.firewall to append items instead of replace 

To maintain consistency with the other options this changes firewall to
combine the existing settings from the image template with the settings
from the blueprint.

Also updated the docs, added a new test for it, and sorted the output
for consistency.

Numeric ports, or their names from ``/etc/services`` can be used in the ``ports`` enabled/disabled lists.
The blueprint settings extend any existing settings in the image templates, so if ``sshd`` is
already enabled it will extend the list of ports with the ones listed by the blueprint.
If the distribution uses ``firewalld`` you can specify services listed by ``firewall-cmd --get-services``
in a ``customizations.firewall.services`` section::

Note that these are different from the names in ``/etc/services``, and only ``enabled`` is supported.
Remember that the ``firewall.services`` are different from the names in ``/etc/services``.
Both are optional, if they are not used leave them out or set them to an empty list ``[]``. If you
only want the default firewall setup this section can be omitted from the blueprint.
