[fix] Setup rate limiter for TestChunksEnqueueFailed to reduce flaky

[RobertIndie]

Fixes #980

Motivation

The root cause of the flaky test is the producer publishes rate may be too large. This causes the producer doesn't even have enough messages in the publish queue. So there may not be the error producer send queue is full: ProducerQueueIsFull in some case.

Modifications

• Setup publish rate limiter for the topic in TestChunksEnqueueFailed to reduce flaky.
