[question] Add a few case studies to the docs

I think it would be pretty useful to do one or more case studies on how (real) large projects are using conan in their day-to-day operations. Topics like:
- Remote setup
- How to
- Add a new package
- Update a new package
- Lock packages
- Level of redundancy
- etc.
- Team roles (one person in charge of conan stuff or...)

I think this will help people with ideas, start discussions on the "proper" way to do this, and motivate features to better serve the community.

- [X] I've read the [CONTRIBUTING guide](https://github.com/conan-io/conan/blob/develop/.github/CONTRIBUTING.md).
