[GH Example] Friction points from Katacoda

[texasmichelle]

Katacoda recently created a scenario out of the GitHub issue summarization example and ran into a number of frustrating issues. The following items need to be addressed in order to turn this example into a platform-independent self-contained unit for use in a wide number of environments.

Could we follow an approach similar to using a bootstrap container as being discussed in kubeflow/kubeflow#673

The idea is users would do something like
kubectl create -f http://github.com/kubeflow/examples/ghissue-bootstrap.yaml
kubectl exec -it gh-bootstrap /bin/bash
quickstart.sh

The goal is that quickstart.sh would set everything up and try to optimize things for their config. This gives them a shell they can drop into with all the tools/code they need.

Could Katacoda reuse these container images?
