Add test stage and job to auto deploy/devops templates

Once we have auto CI, we need to add the test job and stage to the Auto DevOps template.

---

Was:

The current auto deploy templates for OpenShift and Kubernetes only do build and deploy steps, but no tests. We should be encouraging and supporting tests as part of our best practices. The problem is since the template is language and framework agnostic, we have no idea how to actually test their particular app. Perhaps we could put commented-out placeholder jobs in there? But also, we want the auto deploy template to work for the idea to production demo, which does need to show off the test stage. I guess the demo could uncomment the tests.

It seems that we could use special: test scripts of heroku buildpacks: https://github.com/heroku/heroku-buildpack-ruby/tree/master/bin

This is exact documentation: https://devcenter.heroku.com/articles/testpack-api

Looks like Herokuish doesn't yet support that. Maybe get them to update their buildpacks and contribute support for tests.

This is basically covered by Auto CI (using Heroku CI): https://gitlab.com/gitlab-org/gitlab-ce/issues/26941, but leaving this as an explicit task to add the test job to the Auto DevOps template.
