Replace current nodejs+mongo sample with a better one

[l0rd]

Is your enhancement related to a problem? Please describe.

Current nodejs mongo sample is not an appropriate sample as described in #14009
It also lacks a kubernetes yaml to deploy in on kubernetes

Describe the solution you'd like

Add a sample based on cloud code sample with instructions to build and deploy it on k8s and openshift (using the k8s and OS vscode extensions).

[tsmaeder]

The outcome of this would be a devfile with appropriate commands.
Not sure how to deliver the instructions, though: i would guess a separate document somewhere?

[tsmaeder]

@l0rd we don't have a place to put documentation on samples (from foreign repositories). Can you suggest where to put this?

[svor]

@l0rd as I understand cloud code samples where created to work with Google Cloud Code - it's an extension for VSCode which we don't support at the moment. So I am not sure if it is possible to deploy this sample to remote cluster by kubernetes plugin.
Does Kubernetes Plugin allows us to deploy applications to remote cluster from che.openshift.io? Do we have such experience?

[l0rd]

@tsmaeder @svor we want to build something similar to that example but not use that exact repository. The main difference with current che is that cloud code samples has been designed to be deployed on a Kubernetes cluster and have, in the kubernetes-manifest folder, all the yamls to deploy the application.

In other words the outcome for this issue would be a new sample in the che-samples organisation + a modified devfile in the devfile registry.

@svor on openshift we should use the OpenShift VS Code extension and yes we should be able to use it on che.openshift.io to deploy a k8s application there.
