Hi all!

This is to let you know that Toolforge continuous jobs now support health-checks!

To use it you need to provide `--health-check-script ./script.sh` while creating your job. You can also provide the script as a string like this `--health-check-script "cat /etc/os-release"`. Toolforge will periodically attempt to execute your health-check script inside your running job and will restart your job if the script completes with an exit code of 1.

Note: if you use a script file for health-check, do not forget to make the file executable (chmod u+x script.sh). If toolforge can't execute your health-check script, your job will never start.

Also a reminder that you can find this and smaller user-facing updates about the Toolforge platform features here: https://wikitech.wikimedia.org/wiki/Portal:Toolforge/Changelog
