Introduce docker-compose

This commit introduce two compoments:
lavalab-en.py which generate:
- device files
- conmux config files
- users files
- tokens files
- udev rules for host
- final docker-compose.yml file
Except of docker-compose.yml, all other files are ignored for the moment
and will be handled by a following commit.

docker-compose:
The docker compose permits to building and running easily lava-docker
images.
It permit also to remove some contraints like knowing the
LAVA_SERVER_IP/LAVA_MASTER.
