4. In transport
- modify JobDriverReport to carry new AvgTimeForWorkItemsSkewedByByActive (from JD)

> The Resource Manager (RM) employs a mean work item completion time published by the Orchestrator
(OR) to predict Job Processes (JP) usage for resource allocation.  Presently this mean only
considers completed work items, not active ones, and therefore may not reflect the benefits
of more resource allocation to a Job.
> A revised algorithm for calculating the work item prediction mean is:
> 1. calculate mean of completed work items
> 2. find active work items > completed mean
> 3. calculate new mean comprising completed + longer active work items
> 4. publish same
