-----------------------------------------------------------

Patch-1: in this patch, add the simple logic to give the default memory/vcore 
values to the queues if no configuration is set for such queues. A new 
configuration "yarn.scheduler.capacity.default-queue-maximum-allocation" is 
added to set the queue default for maximum allocation.

I didn't implement queue inheritance since feel this would keep the 
configuration simpler. Let me know if it's needed and I can do that in the 
followup.

> YARN-1582 adds the support of maximum-allocation-mb configuration per queue 
> which is targeting to support larger container features on dedicated queues 
> (larger maximum-allocation-mb/maximum-allocation-vcores for such queue) . 
> While to achieve larger container configuration, we need to increase the 
> global maximum-allocation-mb/maximum-allocation-vcores (e.g. 120G/256) and 
> then override those configurations with desired values on the queues since 
> queue configuration can't be larger than cluster configuration. There are 
> many queues in the system and if we forget to configure such values when 
> adding a new queue, then such queue gets default 120G/256 which typically is 
> not what we want.  
> We can come up with a queue-default configuration (set to normal queue 
> configuration like 16G/8), so the leaf queues gets such values by default.
