/**
 * Represents credentials received from relative URI specified in the ECS container.
 *
 * This class will request refreshable credentials from the relative URI
 * specified by the AWS_CONTAINER_CREDENTIALS_RELATIVE_URI or the
 * AWS_CONTAINER_CREDENTIALS_FULL_URI environment variable. If valid credentials
 * are returned in the response, these will be used with zero configuration.
 *
 * This credentials class will by default timeout after 1 second of inactivity
 * and retry 3 times.
 * If your requests to the relative URI are timing out, you can increase
 * the value by configuring them directly:
 *
 * ```javascript
 * AWS.config.credentials = new AWS.ECSCredentials({
 *   httpOptions: { timeout: 5000 }, // 5 second timeout
 *   maxRetries: 10, // retry 10 times
 *   retryDelayOptions: { base: 200 } // see AWS.Config for information
 * });
 * ```
 *
 * @see AWS.Config.retryDelayOptions
