Description

Currently we need to set queue with guaranteed resources.
example:

queues:
          - name: root
            submitacl: '*'
            queues:
              - name: queue1
                submitacl: '*'
                maxapplications: 12
                resources:
                  guaranteed:
                    {memory: 6290G, vcore: 816}
                  max:
                    {memory: 31450G, vcore: 4080}

It will be convenient to support percentage, so that we can configure queue without calculating the actual number.

queues:
          - name: root
            submitacl: '*'
            queues:
              - name: queue1
                submitacl: '*'
                maxapplications: 12
                resources:
                  guaranteed:
                    {memory: 20%, vcore: 20%}
                  max:
                    {memory: 31450G, vcore: 4080}
