add examples support for draft info

[davidgamero]

Description

Add additional information for variable suggested example values in draft.yaml

These are added to enrich draft info output

• rename "info integration test" to "info e2e test" since it doesn't integrate with anything

Please note the following is a breaking change: Update the draft info response to fit the following json format that allows example values and better captures the intent in JSON
