Implement fbs schema & json to fbs converter tool

[Thomas-Mikhael]

• Define the .fbs schema file that mirrors the existing JSON configuration structure.
• Build a JSON-to-FlatBuffer converter tool for generating FlatBuffer config from existing JSON configurations
• Flag to control compiling the Flatbuffers (--config=flatbuffers), default is off
• PyTest for the tool

As discussed via Slack - I love that we go for the Flatbuffers support and the contribution you perform here! But it would be very welcome to see the roadmap and map for its qualification before continuing here. Stating again: This does not require a full and ready qualification, we would just like to judge if the qualification at the end can succeed.
