> Typical collection admin commands are long running and it is very common to have the
requests get timed out.  It is more of a problem if the cluster is very large.Add an option
to run these commands asynchronously
> add an extra param async=true for all collection commands
> the task is written to ZK and the caller is returned a task id. 
> as separate collection admin command will be added to poll the status of the task
> command=status&id=7657668909
> if id is not passed all running async tasks should be listed
> A separate queue is created to store in-process tasks . After the tasks are completed
the queue entry is removed. OverSeerColectionProcessor will perform these tasks in multiple
threads
