Prevent cli from taking new job after receiving a signal

[gaetan-craft]

Feature description

After receiving a signal (for example SIGUSR), the cli worker stop taking new tasks and exit when the last task he locked is over. The ixit part is nor mandatory

Motivating example

A host running cli worker need to be restarted, for example because of security patches to be applied. I'd like to be able to spawn a new host to take the tasks and sunset the other host letting him finish its running tasks

This is already the case, I think? It's called "graceful shutdown". It seems we don't have much in the way of documentation around it though!

Oh my bad, sorry, didn't saw this in the documentation.

Help surfacing it better in the docs would be appreciated!
