> If we're using weight mode, we have much more freedom when it comes to 
> placement rules.
> In YARN-10525, weight conversion became the default in {{fs2cs}}. This also 
> means that we can support nested rules properly and also queues can be 
> created under {{root}}. 
> Therefore, a lot of warnings and validations inside 
> {{QueuePlacementConverter}} are not necessary and only relevant if the user 
> chose percentage-based conversion in the command line.
> Also remove unnecessary stuff in the RuleHandler which are already supported:
> * SPECIFIED_NOT_FIRST
> * USER_MAX_APPS_DEFAULT
> * USER_MAX_RUNNING_APPS
