[metrics]: AWS/PrivateLinkService can't get metric data

[huoshuaibing]

Context information

• AWS service:
• CloudWatch namespace: AWS/PrivateLinkService
• Link to metrics documentation for this service:
• AWS region of the exporter: ap-northeast-1
• AWS region of the service:

Exporter configuration

```yaml -aws_dimensions: - ServiceId aws_metrics_name: EndpointsCount aws_namespace: AWS/PrivateLinkServices aws_statistics: - Maximum ```

Exporter logs

```log ``` ### What do you expect to happen? ### What happened instead?

Could you please show us what aws cloudwatch list-metrics --namespace AWS/PrivateLinkServices is for you?

One thing I find suspicious is that the documentation lists the dimension as Service Id (with a space), but I cannot see what it's like in actual CloudWatch because I don't use PrivateLink.

@matthiasr Yes, the dimension is Service Id
