Description

The new event messaging system acts as the foundation for sending and receiving events between Stratos modules. However there is no mechanism to listen to incoming events (within the context of a module) without overriding the event processors.

Event Flow:
Event -> Event Publisher -> Message Broker -> Event Receiver -> Event Processor -> Event

The idea of this task is to implement a such event listener model which could provide functionality to add event listeners to event processors and receive event notifications when an event is received and processed.
