Description of problem:
Create a quota with decimal numbers, message shows like：
Invalid value: "100m": must be an integer
It's correct for CPU, but not for other resources.


Version-Release number of selected component (if applicable):
openshift v1.1.4-274-g1b00abe
kubernetes v1.2.0-36-g4a3f9c5
etcd 2.2.5

How reproducible:
Always

Steps to Reproduce:
1. Create a project
# oc new-project qwang1

2. Apply quota with decimal numbers to a project 
# cat quota-d.yaml
apiVersion: v1
kind: ResourceQuota
metadata:
  name: quota-d
spec:
  hard:
    cpu: "0.20"
    memory: "1.5Gi"
    persistentvolumeclaims: "0.10"
    pods: "0.10"
    replicationcontrollers: "0.20"
    resourcequotas: "0.1"
    secrets: "0.10"
    services: "0.5"

# oc create -f quota-d.yaml -n qwang1 --config=/home/openshift.local.config/master/admin.kubeconfig 


Actual results:
2. [root@ip-172-18-3-170 home]# oc create -f quota-d.yaml -n qwang1 --config=/home/openshift.local.config/master/admin.kubeconfig 
The ResourceQuota "quota-d" is invalid.

* spec.hard[resourcequotas]: Invalid value: "100m": must be an integer
* spec.hard[secrets]: Invalid value: "100m": must be an integer
* spec.hard[services]: Invalid value: "500m": must be an integer
* spec.hard[persistentvolumeclaims]: Invalid value: "100m": must be an integer
* spec.hard[pods]: Invalid value: "100m": must be an integer
* spec.hard[replicationcontrollers]: Invalid value: "200m": must be an integer


Expected results:
It's better to give messages like this:
* pods: invalid value '0.10', Details: must be an integer
