Subject: [PATCH] fix: gracefully exit on sigterm
The purpose is to avoid duniter database corruption on `docker stop`.
Before that sigterm was ignored, causing docker instance being force-killed
on `docker stop` command after the related timeout expiration.
Exerpt from the `docker stop` manpage:
> The main process inside the container will receive SIGTERM, and after a
> grace period, SIGKILL
