Improve logging in shell scripts

[LoicPoullain]

Issue

• It is not possible to use a log context in shell scripts or any services called from a shell script.
• When reading logs, it is not possible to aggregate logs through the execution of a given script as for an HTTP request.
• When a script succeeds or fails, no message is logged.
• Errors thrown in shell scripts are logged using console.error and not the logger which is not handy. When running a shell script in production, we may want to print the logs using a JSON format for example.

Solution and steps

• Use logger.error instead of console.error in "npx foal run”
• Allow to use log context in shell scripts
• Add a script ID and the script name to log context when running a script
• Log if script run completed or failed
• Pass logger as third argument to the script

Checklist

• Add/update/check docs (code comments and docs/ folder).
• Add/update/check tests.
• Update/check the cli generators.
