 * @Description: API for modifying the shard number of a Redis database instance.
 * This module provides the necessary implementations to handle requests and responses for modifying the shard number
 * of a Redis database instance in the Volcengine environment. It includes traits implementations for converting requests
 * to HTTP-compatible formats and parsing HTTP responses into structured data.
