> In a very large cluster the OverSeer is likely to be overloaded.If the same 
> node is a serving a few other shards it can lead to OverSeer getting slowed 
> down due to GC pauses , or simply too much of work  . If the cluster is 
> really large , it is possible to dedicate high end h/w for OverSeers
> It works as a new collection admin command
> command=assignRole&whitelist=overseer&node=node1_name&node=node2_name
> If a node is whitelisted for overseer it gets preference over others when 
> overseer election takes place. If no whitelisted servers are available 
> another random node will be picked up
