   ### Description of PR
   
   Queue capacity could be set in partition view even though the queue does not 
have access to that label. Leaving the only queue's label capacity in 
/scheduler-conf endpoint. E.g. 
   
   ```
   <property>
   
<name>yarn.scheduler.capacity.root.default.accessible-node-labels.label3.capacity</name>
   <value>100</value>
   </property>
   ```
   Resulting into a bug when the label is deleted and created a new queue. 
Detail in the jira ticket description.
   
   Therefore, a new validation is needed to make sure the queue has access to 
the label before allowing to set capacity in the partition view. Vice versa, 
the accessible label could not be removed if the queue has capacity in that 
partition. Both have to be changed at the same time.
