> QueueMetrics#QUEUE_METRICS is a static map, which is a source of multiple bugs eg. YARN-11152.
> The current scenario could be reproduced by adding queues one at a time via the mutation API.
>  # Validate adding queue1 via validation API
>  # Validation API instantiates a new CS, with a new Configuration, that instantiates a ConfigurationProperties
>  # QueueMetrics does share the same QUEUE_METRICS cache with the original CS, where there is now a Metrics object that belongs to the new CS
