While the default maps are mostly empty this sets the groundwork for
distribution specific defaults. The layout is based on the formula
template.
BREAKING CHANGE: `map.jinja` has been upgraded from using `pillar.get`
to `config.get`.
If the formula was ran on a system that reported an os_family that
wasn't one of "Debian", "RedHat", "Arch", "Suse" then the map.jinja
template would fail to render with "'NoneType' is not iterable.
This occurs because grains.filter_by will return None when it fails
match the grain to the input dictionary. The value is then blindly
passed into a dict.update() which causes the failure.
In this patch we ensure that the default values, as defined in
defaults.yaml, are always applied when grain matching fails.
