- Update baseSetRunlevel() function
  * support custom systemd target names
- Update service support functions
  * remove obsolete suseCloneRunlevel and suseActivateServices
  * use chkconfig instead of insserv
  * enhance suseService to be called with on|off and
    sysVInit runlevels like chkconfig supports it. For
    systemd this value would be ignored
- Remove suseCloneRunlevel calls from EC2 and Xen guest
  templates. They are obsolete since sysVInit has been
  replaced with systemd
