These aren't intended to function; they're here to allow the use of
file.recurse on the provider folder, without requiring the user
to provide pillar data for templates they're not using.
This commit also provides a more concrete example of a 'host' to
be saltified. Users can do
salt-cloud -p make_salty someinstance
or
salt-cloud -m /etc/salt/cloud.maps.d/foo.conf
Either which way the online docs should really be updated with more
concrete examples.
