Rabbitmq connection setup callback

[livius-ungureanu]

Problem:

The ConnectionActor of the rabbitmq-client library offers the possibility to register a connectionSetup callback that is called every time it manages to connect to RabbitMQ. But op-rabbit currently does not expose such a connectionSetup callback in the RabbitControl constructor so it should as user's of op-rabbit should be allowed to register a connectionSetup callback in order to know when a connection goes up or down.

Does using GetConnectionActor not solve the problem for you?

[livius-ungureanu]

As op-rabbit user I am interested for example on logging an alarm instantly and _asynchronously _ when the RabbitMQ connection goes down(and this can be achieved only by registering the connectionSetup callback as the connectionSetup registering is propagated into the amqp driver).

Using GetConnectionActor , the user would be forced to regularly query the ConnectionActor state which is not acceptable.
