Description of problem:
When scaling process failed due to resource restrictions, it will stop to create new pods, instead of always showing "scaling to 11...." it's better to give warning info telling quota/limit exceed

Version-Release number of selected component (if applicable):
openshift v1.3.0-rc1+7bb3e69
kubernetes v1.3.0+52492b4
etcd 2.3.0+git

How reproducible:
Always

Steps to Reproduce:
1.Create quota and limits for project "test"
# oc create -f https://raw.githubusercontent.com/openshift/origin/master/examples/project-quota/quota.yaml -n test
# oc create -f https://raw.githubusercontent.com/openshift/origin/master/examples/project-quota/limits.yaml -n test
2.Create DC for project "test"
# oc run testdc --image=aosqe/hello-openshift
3.Wait deployment complete
4.Scale DC
# oc scale dc/testdc --replicas=11
5.Check RC testdc-1 events on web console, after creating 7 pods, server could not create more pods since quota exceed
Error creating: pods "testdc-1-" is forbidden: Exceeded quota: quota, requested: memory=100Mi, used: memory=700Mi, limited: memory=750Mi 
6.Check pods on overview page

Actual results:
6. It keeps show "scaling to 11...." in pod donut text

Expected results:
6. Since no more pods could be created due to quota restrictions, it's better to give warning info telling quota exceed instead of always showing "scaling to 11...."
