Vanir next

[daechoi]

Be advised that this is a work in progress. Please do not merge to master. This PR adds Makefile and docker-compose services to add Kafka and Zookeeper for Vanir 2.0 initiative. Vanir 2.0 leverages the block explorer to start pushing the data asynchronously to Kafka topics to be used in other API data services in realtime, rather than polling for data in Mongo DB with corn job. Please do not merge to master as it is subject to much stabilization and active development such as Kafka topics. Thanks.
