[Hawkular-dev] Cassandra Cluster with docker.

[Ruben Vargas Palma]

Hello Stefan.

Yes, initially I was working using docker without docker-compose, but 
for convenience and because I didn't know the restriction about compose, 
I decided to use compose at the end. I'll update my repository with the 
work that I have on bash.
