Description

The Fetcher class is used internally by the KafkaConsumer to fetch records from the brokers. There is ongoing work to create a new consumer implementation with a significantly refactored threading model. The threading refactor work requires a similarly refactored Fetcher.

This task involves copying the relevant tests from FetcherTest and modifying them to fit a new unit test named FetchRequestManagerTest.
