Updated to new kafka client version with an option to connect to secured kafka cluster

[satendra-sahu]

Made changes to support new kafka client versions. Has an ability to connect to secured kafka cluster using JaaS configuration file.

Following are the changes:

• Added following properties to application.yml

   kafka:
       env: local
       brokerConnect: localhost:9092
       isSecured: true
  
   zookeeper:
       connect: localhost:2181
  

• To run the application jaas file should be present in the user.dir. jaas config file is picked up based on the env specified in kafka.evn property. Ex if env=local then "kaas_local_jaas.conf" will be used for authentication.
