Mountpoint for Amazon S3 and Mountpoint for Amazon S3 CSI driver add monitoring capability

You can now monitor Mountpoint operations in observability tools such as Amazon CloudWatch, Prometheus, and Grafana. With this launch, Mountpoint emits near real-time metrics such as request count or request latency using OpenTelemetry Protocol (OTLP), an open source data transmission protocol. This means you can use applications such as CloudWatch agent or the OpenTelemetry (OTel) collector to publish the metrics into observability tools and create dashboards for monitoring and troubleshooting. Previously, Mountpoint emitted operational data into log files, and you needed to create custom tools to parse the log files for insights. Now, when you mount your Amazon S3 bucket, you can configure Mountpoint to publish the metrics to an observability tool to proactively monitor issues that might impact your applications. For example, you can check if an application is unable to access S3 due to permission issues by analyzing the S3 request error metric that provides error types at an Amazon EC2 instance granularity. Follow the [step-by-step instructions](https://github.com/awslabs/mountpoint-s3/blob/main/doc/METRICS.md) to set up the CloudWatch agent or the OTel collector and configure Mountpoint to publish metrics into an observability tool.
