> When the reInitializeQueue command is fired or when RM starts up, a bunch of logs related to queue structures are printed, which is not easy to read.
> We can make it simpler with a structured format, like: 
> {code}
> root (capacity = 1.0, max-capacity=1.0 etc.)
>   | --  queue1 (capacity = 0.0, max-capacity = 0.5 etc)
>   | --  queue2 
>   | --  .....
> {code}
> This makes much easier for human read and debug.
