Description of problem:
Set quota by cluster-admin and then create a over sized imagestream from client side. Server returns 201. Describe IS from server side doesn't show "Quota Usage" 

Version-Release number of selected component (if applicable):
oc v1.1.3-483-g28cba69
kubernetes v1.2.0-alpha.7-703-gbc4550d

How reproducible:
Always

Steps to Reproduce:
1. Cluster-admin create quota "openshift.io/imagestreamsize": "0.1Gi" for a user's project:
{
  "apiVersion": "v1",
  "kind": "ResourceQuota",
  "metadata": {
    "name": "quota"
  },
  "spec": {
    "hard": {
      "memory": "1Gi", 
      "cpu": "20", 
      "openshift.io/imagesize": "5Gi",
      "openshift.io/imagestreamsize": "0.1Gi",
      "openshift.io/projectimagessize": "40Gi",
      "pods": "10",
      "services": "5",
      "replicationcontrollers":"5",
      "resourcequotas":"1"
    }
  }
}
2. User login from client side, create a over sized imagestream.
i.e. Use https://github.com/openshift/origin/blob/master/examples/sample-app/application-template-stibuild.json
or use docer.io/xiaocwan/python-33-centos7-practice (156 MB) as following:
{
  "apiVersion": "v1",
  "kind": "ImageStreamList",
  "items": [
    {
      "apiVersion": "v1",
      "kind": "ImageStream",
      "metadata": {
        "name": "python"
      },
      "spec": {
        "dockerImageRepository": "xiaocwan/python-33-centos7-practice"
      }
    }
  ]
}
# oc create -f ispython.json

3. On server side, cluster-admin describe is for this project
`oc describe is python -n xiaocwan2-py`

Actual results:
Step2:# oc create -f ispython.json --v=8

Expected results:
Step3: Should return error, I believe should return 403.
Step4: If create Is first and then the quota, should have the following described
 "Quota Usage:        0MiB / 156 MiB"

Additional info:
If create over sized IS first and then create quota, the "Quota Usage" could be described which is correct.
