Minor Description
Currently Connect depends on two topics: one for storing connector configuration, and other for source connector offsets. In KAFKA-3093, we add another topic to store connector/task statuses, and later it might make sense to use additional topics (e.g. for metrics?). To make it easier for users to configure these topics, it would make sense to have a configuration option "storage.topic.prefix" (or similar) to basically serve as a namespace for the Connect instance. Connect could then create the topics automatically with a default suffix for each storage.
