Requesting help with OpenStack configuration files

Dear OpenStack team,

I’m a Ph.D. student in software engineering at the ETS Montreal, University of Quebec working on the quality and configuration of web-based software systems.
I’m particularly interested in analyzing configuration files from different OpenStack files. One of the main challenges I am currently facing is the proper identification of configuration files. I’m mostly confused between the python files used for production and the python files used for configuration. I am kindly requesting your precious help with the following questions:

1- How to distinguish between python files used for configuration and python files used for production? It will be very helpful if there are some configuration-based patterns (eg, textual patterns or expressions) that we can find in python files to help us distinguish between source code and configuration files?

2- Certain python files use the oslo_config to access and define configuration options. Could "all" these python files be considered as configuration files? For example, the following python file of the keystone project: keystone/keystone/conf/, is it considered a source code or configuration file?

3- Why are there different source code and configuration repositories for OpenStack projects (eg, nova and puppet-nova)? For instance, does the OpenStack-nova service have some configuration files in its repository and have the puppet-nova as a separate configuration repository as well?

Thank you very much in advance for your time and your help!

Kind regards,
Narjes Bessghaier
