Fix close blocked

[nodece]

Motivation

When a consumer or producer reconnects to the broker, the event loop handling the reconnection becomes occupied, preventing the execution of the close command. This can result in the inability to properly close the consumer or producer, leading to potential resource management issues.

Modifications

• Introduce passing a context to the retry function. This ensures that when the context is completed or canceled, the retry logic is interrupted and stops further attempts.
• Modify the producer.Close and consumer.Close methods to call the associated context.CancelFunc to cancel the reconnection attempts.
