    Add quotes around the cinder_iscsi_ip_address value

    In I783e939ae304385674909bfd9f1cac95e04cef22 we add brackets around
    the cinder_iscsi_ip_address if IPv6 but that causes hiera to try
    mapping the value into an array, while it isn't. This change adds
    quotes around the brackets.
