In the dev container, we start only a handful of systemd services. Some recent changes seem to have removed the automatic start of some services:

• tuleap-workers service should start automatically. Without it, async actions are not done and SYSTEM_CHECK complains with a warning
• postfix service should start automatically. Without it, emails are never sent to Mailhog container
• sshd service should start automatically. Without it, devs are unable to interact with Git via SSH. It seems that SSH host keys are not created automatically anymore.
