    Update Fuel CI script to use puppet 3.8

    This change updates the scripts used by Fuel CI to pull in puppet 3.8
    rather than 3.4.

    In order to support testing under Puppet 3.8, we have to setup the
    puppet settings as part of our overrides setup. This is due to a change
    after 3.4 where these settings are no longer setup as part of the
    TestHelper inititalize call. This was done as part of PUP-11118.
    Without setting up up the settings, rspec may error when we attempt
    to access the Puppet scope or functions.
