The JobSchedulerCheckRunHistory should be available with pre-processing monitors

Current Situation

The JobSchedulerCheckRunHistory implementation is available as a job only. Therefore to check a predecessor job in a job chain an extra job node has to be added that references this job to check for the run of a predecessor.

Desired Behaviour

It should be possible to define a pre-processing monitor to check the run of a predecessor job or job chain.

• com.sos.jitl.checkrunhistory.JobSchedulerCheckRunHistoryProcessBefore
  • Implements the check in the api method spooler_process_before
• com.sos.jitl.checkrunhistory.JobSchedulerCheckRunHistoryTaskBefore
  • Implements the check in the api method spooler_task_before

The difference is that when calling spooler_process_before the API methods spooler_init already have been called. The task already is up and running and the methods spooler_close and spooler_exit will be called (if implemented). When using spooler_task_before the pre-processor will prevent the task to start.
