Standardize parameters location (running parameters vs config.py)

[zabealbe]

Parameters location should be decided based on their portability.
For example for flatbuffers-generator: flatcc binary path is always the same? No, in github actions flatcc a musl precompiled binary pulled from a repo, placed in a directory that is not in PATH.
On the other hand network.json is in a standard path for the whole project, it doesn't matter if you run the project on a workstation, over github actions or on your own laptop, thus it should be specified on the config.py.

As a rule of thumb parameters that might change MUST be implemented as running parameters in such a way to avoid edits to config.py that might result to a commit that modifies the remote config.py.
