After creating a persistent volume, check the persistent volume information. 'Reclaim Policy' and 'Message' can't show up correctly


Version-Release number of selected component (if applicable):
oc v0.6.0.1-38-g0e02a6b
kubernetes v0.17.1-804-g496be63


How reproducible:
always

Steps to Reproduce:
1. Create a persistent volume
persistent-volume.json:
{
  "apiVersion": "v1",
  "kind": "PersistentVolume",
  "metadata": {
    "name": "pv0001"
  },
  "spec": {
    "capacity": {
        "storage": "5Gi"
        },
    "accessModes": [ "ReadWriteMany" ],
    "nfs": {
        "path": "/var/export/vol1",
        "server": "master.cluster.local"
    }
  }
}

[root@master beta4]# oc create -f persistent-volume.json
persistentvolumes/pv0001

2. execute 'oc describe persistentvolumes/pv0001'

Actual results:
[root@master beta4]# oc describe persistentvolumes/pv0001
Name:                pv0001
Labels:                <none>
Status:                Available
Claim:                
Reclaim Policy:        %!d(api.PersistentVolumeReclaimPolicy=Retain)
Message:        %!d(string=)



Expected results:
'Reclaim Policy' and 'Message' should show up correctly.
