Description of problem:
'Add item' and 'Remove item' link in add config files page is not headline case.General rule for patternfly's guidelines is that it should be headline case in link actions or buttons, and OpenShift web console should make consistent with that.

Version-Release number of selected component (if applicable):
v3.5.0.32-1+4f84c83

How reproducible:
Always

Steps to Reproduce:
1.Create DC and ConfigMap
$ oc run myrun --image=aosqe/hello-openshift
$ oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/configmap/configmap.yaml
2.Go to Deployments -> myrun -> Configuration tab -> Click Add Config Files
3.Add values from a configmap as following:
Source: special-config
Mount Path: /data
Make sure Select specific keys and paths is selected
4.Click "Add item"

Actual results:
3. After we select "Select specific keys and paths", there is "Add item" link through which we could add multiple specific keys and paths, but word 'item' is not capitalized
4. After click 'Add item', there is 'Remove item' link, also word 'item' is not capitalized

Expected results:
3. Add item link should be headline case as 'Add Item'
4. Remove item link should be headline case as 'Remove Item'
