Public Preview: Azure Container Apps OpenTelemetry collector support

Azure Container Apps now supports a managed OpenTelemetry collector. Available in public preview, this feature allows you to use open-source standards to send your app’s data. You can use the managed collector to choose where to send logs, metrics, and traces. Data can currently be sent to Azure Monitor Application Insights (logs, traces) or 3rd party product Datadog (metrics, traces). You can currently use ARM/Bicep commands to use OTLP collector.
