Bug 1364017

Description of problem:
Use oc client can't attach or debug a init container.

Version-Release number of selected component (if applicable):
openshift v3.3.0.14
kubernetes v1.3.0+57fb9ac
etcd 2.3.0+git

How reproducible:
Always

Steps to Reproduce:
1.Create a pod with init container.
$ oc create -f https://raw.githubusercontent.com/mdshuai/testfile-openshift/master/initContainer/init-containers-sleep.yaml

2.When the init container is running, attach/debug the init container
$ oc attach hello-pod -c sleep 
$ oc debug pod/hello-pod -c sleep -- /bin/env


Actual results:
[root@dhcp-128-7 dma]# oc attach hello-pod -c sleep 
error: pod hello-pod is not running and cannot be attached to; current phase is Pending
[root@dhcp-128-7 dma]# oc debug pod/hello-pod -c sleep -- /bin/env
error: the container "sleep" is not a valid container name; must be one of [hello-pod]

Expected results:
2. Should attach/debug init container as normal app container.
