Add docker-compose.yml and configurations

#40

I created a docker-compose.yml for my local development environment. I am using this configuration with OSX Yosemite and docker toolbox.
It would be nice if you think this would be fit to the project and give me some feedbacks!

Workaround

docker-compose -p cmb -f docker/docker-compose.yml build
docker-compose -p cmb -f docker/docker-compose.yml up

# This is not the elegant way but needed to initialize cassandra dataset
docker exec -it cmb_cassandra_1 cqlsh -f /tmp/cassandra_1.2.cql.schema

# If the user uses docker-machine, she or he can open it by:
open http://$(docker-machine ip dev):6059/webui/

I'm sorry I found that I added wrong Dockerfile to build the image. I fixed Dockerfile to build jar correctly and it works fine now.
