Restart all foodsharing services after production deployment

What does this MR do?

When we deploy, we need to restart all services to run the current code

• For mailqueuerunner and websocket this needs to be done manually by the deploy user
• For php-fpm this is not needed
• for nginx this is not needed (i think?)

How confident are you it won't break things if deployed?
