[torquedev] New job_must_report pbs_server feature

We would like to add a new feature into the 2.3 and 2.4 Torque branches.  It would allow the server to be configured so that jobs must report to the scheduler and be confirmed by the scheduler before they are cleaned out.  The scheduler uses a pbsD_deljob() with an extend string "purgecomplete=x", which says to purge jobs that have reported to the scheduler and whose completion time is less than or equal to the time specified by "x".  Currently, Moab is the only scheduler that supports this.  A new server attribute "job_must_report" controls this feature and the default behavior of Torque is the same unless that attribute is set.

This feature has been running successfully in production systems for several months now.

The attached file shows the changes to be made in implementing this feature.

Thank you for your time and comments,
Al Taufer
