This modification introduce a breaking change about AMQP queue handling. Now, Almanach use the same terminology as other OpenStack projects. - By default, Almanach listen on the "almanach" topic - The "info" priority is used to receive notifications - The "error" level is used as retry queue - The "critical" level for the dead queue To be compatible with olso_messaging drivers, transport_url must start by "rabbit://" to use the driver kombu.
