Prepare example submissions that KCIDB-ng will accept

[jessesimpson36]

KCIDB-ng is currently in a state where you can spin a test server up, create tokens, and submit samples that the server will accept (which might just accept any json blob at the moment).

According to https://github.com/kernelci/kcidb-ng/blob/ea9f4750d520afd34bdf149efed1e75eb06491aa/SUBMITTERS.md?plain=1#L20 , the 5_03 schema is currently planned for use in kcidb.

1. Prepare your data: Ensure you have all the necessary information ready, including kernel configuration, build environment details, test results, and logs. You can see details about the required fields in the KCIDB-NG schema.

(this is still a moving target as kcidb-ng is still new and in development)

Examples of me submitting something:

> curl -X POST \
  -H "Authorization: Bearer $BEARER_TOKEN" \
  -H "Content-Type: application/json" \
  -k -d @submission.json \
  https://localhost:443/submit

{"id":"fJgX16iPkJ5jnbaJWf7tGki3TuNFqkb4","status":"ok","message":"Received submission fJgX16iPkJ5jnbaJWf7tGki3TuNFqkb4 with size 1732 bytes"}

I'm thinking as a good step 1 to the overall epic of integrating with their new system, we could prepare example snippets that conform to their newer specs, and then begin development on a new script for creating the submission data from the metadata that GKCI gathers.

On this repo, they have a python3 script that will validate the json. so if we create examples, we could have a github actions script that will validate them against the latest versions of the kcidb-io spec.

Still very much a work-in-progress:

I opened the following PR:
GKernelCI/Ghelper#121

It includes a CI workflow that validates the example submission, and the example submission is still pretty well filled out, but I included TODO comments as some gaps that I need to find a solution for.
