> Since we have "yarn cluster -lnl" to print all nodelabels info .But it's not enough,we
should be abale to list nodes collection partitioned by labels,especially in large cluster.
> So  I propose to add an optional argument  "-nodes" for  "yarn cluster -lnl" to achieve
this.
> e.g.
> [yarn@docker1 ~]$ yarn cluster -lnl -nodes
> Node Labels Num: 3
>               Labels                                      
        Nodes
>  <tensorflow:exclusivity=true>           docker1:45454, docker5:45454
>  <spark:exclusivity=true>                   docker2:45454
>  <impala:exclusivity=true>                 docker3:45454
