v0.8.3

Fixed

• (AMQP): Services using @intersect_message endpoints + Clients should now be able to execute long-running tasks without causing disconnects. AMQP message consumers no longer block the AMQP I/O loop, but now handle messages in their own threads; this allows the AMQP I/O loop to continue sending heartbeat frames to the remote broker, preventing the broker from disconnecting the microservice.
