 * KinesisConf - Configuration management for AWS Kinesis API parameters

 * Parameters are categorized into three maps based on which API they apply to:

 * - GetRecords API parameters (max_records, stream_arn)

 * - GetShardIterator API parameters (stream_arn, timestamp)

 * - ListShards API parameters (stream_arn, max_results)

 *

 * Note: Frequently-used parameters (stream, shards, positions) are stored

 * as explicit members in KinesisDataConsumer for better performance.
