             Summary: ActionEventUtils: add support for multiple Event Bus
                 Key: CLOUDSTACK-4775
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4775
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Management Server
    Affects Versions: 4.2.0
            Reporter: Alena Prokharchyk
             Fix For: Future


ActionEventUtils is responsible for publishing events into EventBus. At the 
moment the code defines the Event Bus to publish to, as singleton, assuming 
that there is gonna be only one instance of the Events Bus defined in the 
components.context.xml. Currently only RabbitMQ implements this interface.

In the future we might have multiple instances on the Event Bus configured in 
the system; for instance, one can be RabbitMQ server used by thirdparty app, 
the other - some internal event bus used in the context of the same CS app. 

Summary - need to add a support for publishing events to multiple instances of 
Event Bus.
