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.
Most include do not expect salt to be something else than the usual salt
variable giving access to all the salt modules. Instead we use cfg_salt.
And for consistency we rename the master/minion variables to
cfg_master/cfg_minion too.
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.
