 * - endpoint: The URL of the Milvus server.
 * - username: (Optional) The username for authentication.
 * - password: (Optional) The password for authentication.
 * - token: (Optional) The token for authentication.
 * - fetch: (Optional) An alternative fetch API implementation, e.g., node-fetch for Node.js environments.
 * - baseURL: (Optional) The base URL for the API endpoints.
 * - version: (Optional) The version of the API endpoints.
 * - database: (Optional) The default database to use for requests.
 * - timeout: (Optional) The timeout for requests in milliseconds.
 *
 * Note: This is a base class and does not provide specific methods for interacting
 * with Milvus entities like collections or vectors. For that, use the HttpClient class
 * which extends this class and mixes in the Collection and Vector APIs.
