Marcin Maliszkiewicz 3992d1c2ce alternator: add support for ReturnValuesOnConditionCheckFailure feature ...

As announced in https://aws.amazon.com/about-aws/whats-new/2023/06/amazon-dynamodb-cost-failed-conditional-writes/,
DynamoDB added a new option for write operations (PutItem, UpdateItem, or DeleteItem),
ReturnValuesOnConditionCheckFailure, which if set to ALL_OLD returns the
current value of the item - but only if a condition check failed.

Fixes https://github.com/scylladb/scylladb/issues/14481
