Rancher Cassandra

This container is an extension of the official Docker Cassandra image which adds support for running in Rancher. Specifically, this container allows setting the CASSANDRA_LISTEN_ADDRESS and CASSANDRA_BROADCAST_ADDRESS environment variables to a value of rancher. Setting this value cause the container to discover the container's IP address using the Rancher metadata service. Specifically, the environment variable will be set to the value of the private_ipproperty in the metadata service.
