Amazon Managed Service for Prometheus now supports label-based active series limits

[Amazon Managed Service for Prometheus](https://aws.amazon.com/prometheus/) now supports label-based active series limits within your workspace. This feature helps you manage active series volume across different producers such as applications, services or teams that share a workspace. You can now allocate specific active series limits to different metric producers in your workspace, enabling you to protect your critical metrics. If a sub-set of metrics experience an unexpected surge, only the metrics sharing the same label-based active series limits are throttled. For example, you can set different limits for metrics from different applications using label sets like {app="payment-service", environment="prod"}. If the payment-service application produced an unexpected surge in metrics, only ingested metrics originating from the payment-service application are throttled. This experience is enabled by the new Workspace Configuration APIs. Using these APIs, you can also manage the data retention period of your workspace. You can specify the number of days to retain metrics data within your workspace, before permanent deletion. To get started, visit AMP console's workspace configuration tab or use AWS CLI, SDK, or APIs. Check out the [Amazon Managed Service for Prometheus user guide](https://docs.aws.amazon.com/prometheus/latest/userguide/AMP-workspace-configuration.html) for detailed documentation. This feature is now available in all AWS regions where Amazon Managed Service for Prometheus is [generally available](https://docs.aws.amazon.com/prometheus/latest/userguide/what-is-Amazon-Managed-Service-Prometheus.html#AMP-supported-Regions).
