Fixes #361
While working on #361 I found out it wasn't that easy to introduce the concept of topic in
SimpleMessageQueue
because there wasn't a clear separation between "client" and "server". With other flavors of message queues, the client is the one responsible for managing consumers, while the server is the actual broker service (Redis, Kafka and the likes). But the simple message queue also has a "server" part that acts as an in-memory storage.With this PR, the server and the client are clearly separated, and only
SimpleMessageQueue
derives fromAbstractMessageQueue
, while the server class is just an object. This way, the simple message queue isn't special anymore, and it behaves exactly like the others.
