Add option to terminate jobs that exceed Admission Times

Current Behavior

• Users can specify a timeout for the duration for which a job can exeucte using the syntax HH:MM:SS. When exceeding the timeout, the job will be cancelled.

Desired Behavior

• Users would like to specify the timeout from a fixed point in time during the day (HH::MM:SS). If the job is running at the indicated point in time, then the job will be terminated by the Agent.
  • Termination of a job includes to kill the job, using the same mechanism as the cancel/kill operation.
    • In a later elaboration of the feature jobs will be configurable to accept SIGTERM instead of implicit SIGTERM/SIGKILL in case they exceed the timeout. When cancelling a job by user intervention then SIGTERM/SIGKILL will be applied.
  • Users can assign Admission Times to jobs. They specify the period when a job can run.
    • Current Behavior: If a job exceeds the period specified with its Admission Time, then the job can continue to run.
    • Desired Behavior: users can specify from an option to terminate jobs that exceed the Admission Time's period.
