<details> <summary>Describe shortly what is Zuul</summary> <b>

From Zuul's docs: "Zuul is a Project Gating System. That’s like a CI or CD system, but the focus is on testing the future state of code repositories...

Zuul itself is a service which listens to events from various code review systems, executes jobs based on those events, and reports the results back to the code review system." </b></details>
