DC Metro Maps Workshop: Deprecated Application Template

[dmc5179]

Lab 8 pulls the following template:

oc create -f https://raw.githubusercontent.com/openshift/origin/master/examples/jenkins/application-template.json

Which refers to a deprecated image which doesn't exist: nodejs-010-centos7 And tells the user to edit the template to change that image name to: nodejs-10

Update the lab to use a template that works on its own. It is not a 101 level tasks to edit the template. It looks and feels like we have steps in our lab to fix a broken part of the lab.
