Description of problem:
In user's plan , the Max memory is 2Gi Memory for application. But User can create project quota over 2Gi, such as  limits.memory=10Gi.

Version-Release number of selected component (if applicable):
Online-STG 3.5.5.25
online version:3.5.1.32

How reproducible:
100%
quota.json:
{
  "apiVersion": "v1",
  "kind": "ResourceQuota",
  "metadata": {
    "name": "compute-resources"
  },
  "spec": {
     "hard": {
       "limits.cpu": "4",
      "limits.memory": "10Gi"
    },
    "scopes": [
      "NotTerminating"
    ]
  }
}


Steps to Reproduce:
1.login in online-stg , subscribe a base plan;
2.oc new-project pro2;
3.oc create quota.json -n pro2;
4.oc describe quota compute-resources -n pro2


Actual results:
3.resourcequota "compute-resources" created
4.
Name:        compute-resources
Namespace:    pro2
Scopes:        NotTerminating
 * Matches all pods that do not have an active deadline.
Resource    Used    Hard
--------    ----    ----
limits.cpu    0    4
limits.memory    0    10Gi

Expected Result
Failure in create project quota when the memory is over Max memory the user have.
