Take job size into account in historical run_time

See this idea on ideas.ibm.com

LSF's fairshare includes a RUN_TIME parameter that can track the total time accumulated by a user / group's completed jobs. By weighting this parameter, a user's historic jobs can be accounted for in determining their job priority. This factor does not currently consider job size, however. So, for example, a 10 node job "costs" the same as a 1 node job in determining the priority of queued jobs. There is another factor, JOB_SIZE that tracks the size of running jobs, but it is not tracked for completed jobs. We would like to be able to include the product of the job size and run time in our fairshare calculations. This factor should be allowed to decay over time according to the HIST_HOURS parameter similar to RUN_TIME.
