1. Add cpuset size information to the FJR. …

   We have found that it's difficult to detect when the cpuset (set by
   some batch systems) is limiting the number of cores we can run on.
   
   In one extreme case, the batch system arguments were being done
   incorrectly and 32 cores worth of CMS jobs were being forced onto a
   single core.
   
   This records the current cpuset size to the FJR when CPU information
   reporting is enabled.  The resulting line looks like:
   
       <Metric Name="cpusetCount" Value="1"/>
   
   With this, we hope that experts are more likely to notice that the
   cpuset is different from expectations
