Add a Nodejs CRUD devfile with outer-loop information

[sbose78]

( PR has been created for contextual discussions )

What does this PR do?

Adds a new devfile sample with inner-loop and outer-loop details containing build and deploy guidance.

Source code used in the devfile:
https://github.com/sbose78/nodejs-rest-http-crud/tree/for-devfile

I haven't tested this yet. I've used existing API support, without introduction of anything new.
Inner-loop details copied from https://github.com/devfile/kubernetes-api/blob/master/devfile-support/samples/nodejs-stack.devfile.yaml

I will create follow-up issues for enhancing the devfile to support:

• helm charts
• pod-spec based deployment guidance.
• kubernetes apiVersion & Kind based deployment guidance.
• source-to-image and buildpacks based build guidance.

What issues does this PR fix or reference?

• Copied over inner-loop guidance from https://github.com/devfile/kubernetes-api/blob/master/devfile-support/samples/nodejs-stack.devfile.yaml ( needs fixing and testing )
• Adds a component + command to do a kaniko build
• Adds a component referring to a postgresql deployment + service yaml manifest in the source code repo.
• Adds a component referring to a Dockerfile build in a kaniko container.
• Adds a component referring to a nodejs app Deployment + Route yaml manifest in the source code.
