#61 Mount traefik config directory into l3drun and kill the traefik container before removing network

This reverts commit 2226f696

Make sure that .gitconfig and composer's auth.json exist even before l3drun gets started, not before l3d project container starts as that's too late

Prepare v1.12.0

Prepare release v1.11.0

Forward auth.json into the l3d container in order to let composer use the stored authentication in all projects

#28 Touch the ~/.gitconfig file to make sure it does exist before creating a new container
