Description

While reviewing https://github.com/apache/kafka/pull/10973, we have noticed that `AlterConsumerGroupOffsetsHandler` does not handle the partition errors correctly. The issue is that any partition error fails the entire future returned in the results instead of failing only the future of the corresponding partition. This is a regression that was introduced by KIP-699.
