Description of problem:
Dynamic provision pvc is pending , no pv is created 

Version-Release number of selected component (if applicable):
oc v3.1.1.910
kubernetes v1.2.0-alpha.7-703-gbc4550d
Docker 1.8.2-el7, build a01dc02/1.8.2
kernel 3.10.0-327.10.1.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Create a pvc using below json file
{
  "kind": "PersistentVolumeClaim",
  "apiVersion": "v1",
  "metadata": {
    "name": "claim2",
    "annotations": {
        "volume.alpha.kubernetes.io/storage-class": "foo"
    }
  },
  "spec": {
    "accessModes": [
      "ReadWriteOnce"
    ],
    "resources": {
      "requests": {
        "storage": "3Gi"
      }
    }
  }
}

2. Check PVC status 
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  annotations:
    volume.alpha.kubernetes.io/storage-class: foo
    volume.experimental.kubernetes.io/provisioning-required: volume.experimental.kubernetes.io/provisioning-completed
  creationTimestamp: 2016-03-17T02:39:50Z
  name: claim2
  namespace: chao
  resourceVersion: "934987"
  selfLink: /api/v1/namespaces/chao/persistentvolumeclaims/claim2
  uid: 85be6a47-ebe9-11e5-9fd3-0a40e3e0a381
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 3Gi
status:
  phase: Pending


Actual results:
PVC is pending, no pv is created

Expected results:
PVC should bind to pv
