Add simulated failure handler and/or improve error message

[kpwebb]

Hi, just sharing this as potential improvement for the hello-world example. I was deploying on a multi-machine setup and missed that the example had a random failure by design and thought it was a problem with the networking set up. Might be good to either include [SIMULATED] in the error logs, or offer up a handler that explicitly calls out the failure mode.

Hi @kpwebb,

Thank you for your contribution! I think this is a super fair remark and I can fully see where you are coming from.

• The addition of SIMULATED to the log messages is a good idea, I will definitely take this into account also for all the other quickstarts.
• For the adding of an extra service. I am wondering whether it would be nicer to solve this by adding an env var FAILING=true which causes the service to crash, and by default just letting the handler pass.

I'll have a look at some nice ways to take your feedback into account tomorrow. Thanks again

Thanks for investigating, and the FAILING=true env is a great idea!
