Description of problem:
By specifying -L flag in oc get <resource> command, we expect the existing labels to be listed seprately in columns for this resource, but this currently only work for po,rc and svc, and print empty grids for build,bc,dc and is

origin/cli
M
M

Version-Release number of selected component (if applicable):
oc v1.1-428-ged29520
kubernetes v1.1.0-origin-1107-g4c8e6f4

Steps to Reproduce:
1. oc login openshift, create a new project
2. oc create -f https://raw.githubusercontent.com/openshift/origin/master/examples/sample-app/application-template-stibuild.json, wait for build completes and app pods running
3. Validate if oc get <resource> -L <label1>,<label2>,... can list labels in specified columns successfully:

take buildconfig as example:
<resource>=bc:
$ oc describe bc ruby-sample-build | grep -i labels
Labels:                        name=ruby-sample-build,template=application-template-stibuild
$ oc get bc -L name,template
NAME                TYPE      FROM      LATEST    NAME      TEMPLATE
ruby-sample-build   Source    Git       1

Actual Result:
oc get <resource> -L not be able to list existing labels seprately in columns for build,bc,dc,is
oc get <resource> -L is only able to list existing labels seprately in columns for po,rc,svc (see more details in "additional info")

Expected Result:
oc get <resource> -L should be able to list existing labels seprately in columns for build,bc,dc,is successfully

Additional info:
The behavior of the passed scenarios:
when <resource>=po:
$ oc describe po frontend-1-x9n43 | grep -i labels
Labels:                                deployment=frontend-1,deploymentconfig=frontend,name=frontend
$ oc get po frontend-1-x9n43 -L deployment,deploymentconfig
