Facts update: check several files for needed info

Updated "astute_settings_yaml" and "fuel_version_yaml" facts to
support search for info in several files. This is needed for Fuel
containers. Both facts look for their files in /etc/fuel/ dir
first, then in default locations. Infortmation is takes from
the first file it finds.

- astute_settings_yaml fact search path:
    * /etc/fuel/astute.yaml
    * /etc/astute.yaml

- fuel_version_path fact search path:
    * /etc/fuel/version.yaml
    * /etc/fuel/nailgun/version.yaml
    * /etc/nailgun/version.yaml
