refs #12: Add a new PPC-based LB and eliminate randomness in LBs.
5747b12 
 * IMPORTANT CHANGE: We no longer use random variables in our load
   balancers!  Instead, load balancers calculate how many batches should
   be sent to the CPU while the GPU always take the coproc-ppdepth
   number of batches.  This greatly stabilizes the PPC of GPUs.

 * Now load balancers track the CPU ratio per NUMA node.
