     Returns a valid value for the "source" parameter of a "file.managed"
     state function. This makes easier the usage of the Template Override and
     Files Switch (TOFS) pattern.

       * indent_width: indentation of the result value to conform to YAML
       * use_subpath: defaults to `False` but if set, lookup the source file
         recursively from the current state directory up to `tplroot`

     If we have a state:
