Support user-specific minimum user limit percentage in Capacity Scheduler

      Description

      Currently, in the capacity scheduler, the minimum-user-limit-percent property is per queue. A cluster admin should be able to set the minimum user limit percent on a per-user basis within the queue.

      This functionality is needed so that when intra-queue preemption is enabled (YARN-4945 / YARN-2113), some users can be deemed as more important than other users, and resources from VIP users won't be as likely to be preempted.

      For example, if the getstuffdone queue has a MULP of 25 percent, but user jane is a power user of queue getstuffdone and needs to be guaranteed 75 percent, the properties for getstuffdone and jane would look like this:

        <property>
          <name>yarn.scheduler.capacity.root.getstuffdone.minimum-user-limit-percent</name>
          <value>25</value>
        </property>
      
        <property>
          <name>yarn.scheduler.capacity.root.getstuffdone.jane.minimum-user-limit-percent</name>
          <value>75</value>
        </property>
