Update docker-compose.yml with traefik 1.0RC2

Hi,

With traefik 1.0RC2, seems the line is now --docker.endpoint=tcp://192.168.200.1:2378:

command: --web --docker --docker.domain=picocluster --logLevel=DEBUG --docker.endpoint=tcp://192.168.200.1:2378 --docker.watch

instead of:

command: --web --docker --docker.domain=picocluster --logLevel=DEBUG --docker.endpoint tcp://192.168.200.1:2378 --docker.watch

Otherwise, it refuses to start and says:

traefik_1  | Error : flag needs an argument: --docker.endpoint

To update once new hypriot/rpi-traefik is pushed to docker-hub :-)

Rename repo to support Intel demos?

Should we rename this repo to support other CPU platforms as well?

How should be structure the demos

• armhf or rpi folder + amd64 folder

Or each demo has a sub directory with amd64 / rpi?
