Very draft example for #464

[Sammo98]

Description

Example of how a new body request variant could be added for file #464

This was chucked together just to get an idea of how it could work, a barely working example below:

  file_json: !request
    name: Raw JSON
    method: POST
    url: "{{host}}/anything"
    headers:
      Content-Type: application/json
    body: !file test.json

Per my comment, I'm going to close this since this will be handled by the upcoming configuration changes.
