Rely on autorequire for config resource ordering

Currently we specify the ordering of config resources wherever it is
necessary based on the presence of the file it will write to, or the
presence of the package in charge of providing the file it will write
to.

Those kind of ordering can be specified directly at the resource level
using the autorequire mechanism. With this patch, any config resource
will make sure the package in charge of providing the file will be
installed first.
