[Container-tools] Prepackaged OpenShift template with CDK

[Lalatendu Mohanty]

We are planning to ship one OpenShift template  by default in the CDK 
Vagrant box  as an user should be able to setup OpenShift and run an 
example without connecting to internet. [1]

Also we are planning to use nodejs-ex for the same [2].  Let us know if 
you have some suggestion for us on this.
