helk-elasticsearch
+ Updated main yml config to set most of the settings via environment variables via docker-compose
+ Trial docker-compose file now has ELASTICSEARCH_PASSWORD environment variable set/available. Trial Dockerfile was deleted since the elasticsearch_password update is now taken care of by the internal elasticsearch docker script that is comes with the official elasticsearch docker image.

helk-kafka-broker
+ split entrypoint script to have topics creation separate
++ auomated the way how the container checks for the kafka broker port availability. If the port is open, then it attempts to create kafka topics
+ No need to tail kafka logs to keep the container alive after running the kafka start script. It now just starts the broker via Dockerfile CMD command and stays alive.
helk-zookeeper
+ updated entrypoint to only set the main server config
+ zookeeper is now started via Dockerfile CMD command
All
+ Moved all to docker folder. Getting ready to start sharing other ways to deploy helk (terraform & Packer maybe)

Jupyterhub
+ Multiple users and mulitple notebooks open at the same time are possible now
+ Jupytehub now has 3 users hunter1,hunter2.hunter3 and password patterh is <user>P@ssw0rd!
