Change script language from Shell to JavaScript for JITL jobs JobChainStart and JobChainEnd

Current Situation

• The JITL jobs JobChainStart and JobChainEnd are dummy jobs used as start and end node.
• The JITL jobs has script language as Shell and has a Java configuration monitor sos.scheduler.managed.configuration.ConfigurationOrderMonitor. Due to fact that shell script has a Java configuration monitor, JVM is created and destroyed for every execution of shell script.
• For this jobs default max_task is 1, when these jobs are used across many job chains or in a high volume job chain, due to repeated JVM creation, jobs create a bottleneck effect.

Desired Situation

• job sos/jitl/JobChainStart
  • script language="java:javascript" instead of shell
  • idle_timeout="30" instead of default 5 seconds
  • tasks="3" instead of default 1
• job sos/jitl/JobChainEnd
  • remove the java configuration monitor
• Performance should be improved for high volume processing.
