Description of problem:
When we hover the inner circle of resource quota donut, it shows 'xxx available' but the value is wrong, currently the value is the same as used value 

Version-Release number of selected component (if applicable):
4.5.0-0.nightly-2020-04-15-194358

How reproducible:
Always

Steps to Reproduce:
1. cluster admin creates resource quota for project
# cat resource-quota.yaml 
apiVersion: v1
kind: ResourceQuota
metadata:
  creationTimestamp: null
  name: quota
spec:
  hard:
    cpu: "1"
    memory: 750Mi
    pods: "10"
    replicationcontrollers: "10"
    resourcequotas: "1"
    services: "10"
status: {}

# oc create -f resource-quota.yaml -n yapei-1
resourcequota/quota created
2. before we create workloads, check resource quota usage at Administration -> Resource Quotas -> quota details page, it shows 0% used 
3. create some workloads, such as Deployment Config from console using example YAML, after pods are running, check resource quota usage again, it shows 60% used for CPU Request, 40% used for Memory Request in chart
4. hover the inner circle of the chart
5. hover the outer circle of the chart

Actual results:
4. it shows '60 available', '40 available'
5. nothing shows 

Expected results:
4. If inner circle presents usage, it should show correct usage used in this project. 
5. Not sure what's the usage of outer circle
