Lianet Magrans updated KAFKA-14965:
-----------------------------------
Description:
This task introduces new functionality for handling ListOffsets requests for
the new consumer implementation, as part for the ongoing work for the consumer
threading model refactor.
This task introduces a new class named \{{OffsetsRequestManager, }}responsible
of :
* building ListOffsets requests
* process its responses
Consumer API functionality that requires ListOffsets requests are implemented
using this manager: beginningOffsets, endOffsets and offsetsForTimes.
These consumer API functions will generate a ListOffsetsApplicationEvent with
parameters. This event is then handled by the OffsetsRequestManager, who will
build the ListOffsets request and process its responses, to provide a result
back to the API via the ListOffsetsApplicationEvent completion.

This task introduces new functionality for handling ListOffsetsRequests for the
new consumer implementation, as part for the ongoing work for the consumer
threading model refactor.
This task introduces a new class named {{ListOffsetsRequestManager,
}}responsible of handling ListOffsets requests performed by the consumer to
expose functionality like beginningOffsets, endOffsets and offsetsForTimes.
The Offset{{{}Fetcher{}}} class is used internally by the {{KafkaConsumer}} to
list offsets, so this task will be based on a refactored Offset{{{}Fetcher{}}},
reusing the fetching logic as much as possible.
