    Replace hiera('service_names') by hiera('enabled_services')

    In the effort of reducing the number of Hieradata files, the
    service_names parameter previously consummed in puppet-tripleo can be
    replaced by enabled_services which contains the same list.

    It will allow us later to remove the service_names hieradata file.
