> Capacity Scheduler right now schedules multiple containers per heart beat if there are
more resources available in the node.
> This approach works fine however in some cases its not distribute the load across the
cluster hence throughput of the cluster suffers. I am adding feature to drive that using configuration
by that we can control the number of containers assigned per heart beat.
