Change the client to use Pod IP instead of host alias to talk to notification services
Refactor client according to Single Responsibility Principle:
1,extract broker state management logic from daemon module to broker_state_manager
2,extract broker connection management logic from daemon module to broker_connection_manager
3,extract notification handling logic from daemon module to notification_handler
4,move NotificationWorker from daemon module to notification_worker module
5,change broker endpoint from host alias to IP which removes dependency to /etc/hosts
6,add logic to re-setup the broker connection in case of notificationservice pod IP changes
