Add code to calculate the run queue depth of a cpu and iowait depth of the cpu. The scheduler calls in to sched_update_nr_prod whenever there is a runqueue change. This function maintains the runqueue average and the iowait of that cpu in that time interval. Whoever wants to know the runqueue average is expected to call sched_get_nr_running_avg periodically to get the accumulated runqueue and iowait averages for all the cpus.
