CLI: modules package refactor PoC

[musztardem]

Problem

• During the QA phase there were multiple bugs, improvement ideas, inconsistencies found.
• We've noticed that some things require changes of similar things in multiple places in order to work consistently. That suggest there's a room for architectural improvement.
• Over the course of months the requirements for community modules were changing and now we're at point where we already have a good idea how we want things to work. The modules package grew big enough that there's a solid reason to think about incorporating more mature architectural solutions.

Expected output:

• The first command that's going to be refactored is kyma module catalog
• The idea is to do research on approaches that could be used in order to structure the code more efficiently, in a way that would allow for a better scalability, readability and maintainability.
• From the user perspective, the kyma module catalog command should work similarly as the previous version.
• The command should be available under the kyma alpha module catalog command - both versions are still available to the user.
• Prepare the ADR document that will describe solutions used in the refactored code.
