require package 'iscsiuio', handle service 'iscsiuio' (bnc #874795, bnc #881543) 

Just a sidenote, `Service.Status` is a deprecated legacy function and should not be used in new code, as it returns only 0 and -1 . https://github.com/yast/yast-yast2/blob/master/library/runlevel/src/modules/Service.rb#L263

Systemd does not know about status codes. Rather use `Service.active?('iscsi')`.
