[CONTENT] Provide information about CI/CD integration

[d-koppenhagen]

It would be great to have an overview how the listed tools can be integrated in a CI/CD pipeline.
I don't think about concrete implementations but about general things that should kept in mind such as:

• running/testing only parts of the pipeline for affected packages
• test everything in a single pipeline
• deploying only affected packages
• Distinguish between a branch pipeline (run only affected and a master/main branch pipeline)
