Description of problem:
oc process does not emit a non-zero exit code when the template contains an invalid label value

Version-Release number of selected component (if applicable):
oc v1.1.6

How reproducible:
Always 

Steps to Reproduce:
1. Download https://raw.githubusercontent.com/openshift-qe/v3-    testfiles/master/build/ruby22rhel7-template-sti.json

2. Modify the very last 'labels' line (line 479) with an invalid value, like: 
 "label!!": "value1"
3. run oc process on that file: 
oc process -f ruby22rhel7-template-sti.json
      error processing the template "ruby-helloworld-sample": Template "ruby-helloworld-sample" is invalid: labels: Invalid value: "label!!": must be a qualified name (at most 63 characters, matching regex ([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9]), with an optional DNS subdomain prefix (at most 253 characters, matching regex [a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*) and slash (/): e.g. "MyName" or "example.com/MyName"
      {
          "kind": "List",
          "apiVersion": "v1",
          "metadata": {},
          "items": null
      }
