Translate examples from JSON to YAML in 1.0.0-alpha1 DSL

What would you like to be added:

Translate/optimize pre 1.0.0-alpha1 examples.

Examples, like everything else, should be written in YAML, for the sake of readability and to leverage at best the new syntax.

Why is this needed:

Provide, in addition to /ctk/features a good variety of examples.

Depends on:

• #861

@cdavernas I think we can slowly add examples to the examples dir as we progress fixing schema bugs like in #863.

I'll hold this for now once we create a tool to migrate from version 0.8 to 1.0.0. So we can use the former examples to test the tooling. :)

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

@ricardozanini @JBBianchi @fjtirado the examples we have introduced should fo the trick, right? If so, can I close as completed?

@cdavernas In my opinion, we can close that one and add additional examples as we see fit. Maybe, we can add one that use more complex jq expressions, but I understand thats also controversial, becuase JQ is just one expression language and this is not a jq tutorial

We can close this. As soon as I start working on the migration tool, I can revisit the old samples in the 0.9 branch.
