> *Current:*
> - We are reading the top level max-AM percent value for non 'llap' named queue at root
level. 
> Eg: yarn.scheduler.capacity.maximum-am-resource-percent=1
> *Required:*
> AM Percent value should be read as:
> - Fetch the 'AM Percent' value for queue in consideration, if exists, else
> - Return default value as 0.1.
> *Eg:* 
> Say queue in consideration is named: 'xyz' and is at depth 3. Thus, the expected 'key'
config to be read is :
> {noformat}
> yarn.scheduler.capacity.root.abc.xyz.maximum-am-resource-percent=<some value>
> {noformat}
