Introduce an Issue/Emergency Scenario during the monitoring

[gsampaio-rh]

Is your feature request related to a problem? Please describe.
Some attendees asked about real user cases scenarios that we can share/present during DO500. The request comes from the perspective that they want us to share situations that we experienced and how they got addressed (What's already included in our KitBags) but maybe that's an opportunity to introduce an application monitoring/logging/observability exercise in chapter 16.

Describe the solution you'd like
We can "break" the team's applications and purpose them to find the problem so they can experience an issue situation. This will give an opportunity to check traceability, logging and maybe we can use that as an opportunity to implement monitors, or just liveness and readiness probes, in the application.

Describe alternatives you've considered
As this is not a mandatory exercise would be more a question if we have time on the final day to run this practice or just go over the slides.
