    Separate scripts creation tasks for under/overcloud.

    The upgrade/update tasks in tripleo-upgrade started
    with a create-scripts book, which generated most of
    the scripts from the templates. However, this book
    mixed the creation of scripts needed for the overcloud
    as well as for the undercloud. This becomes an issue
    when we want to perform only an undercloud upgrade, as
    we are running tasks intended to the overcloud and it
    might not even exist.
    This patch divides the script creation tasks used for
    the undercloud from the ones used for the overcloud.
