Agent Runtime: ADK telemetry metrics

Agent Runtime: ADK telemetry metrics

Agents deployed to Agent Runtime with Agent Development Kit (ADK) 2.6.0 or later can emit gen_ai application metrics that follow OpenTelemetry's generative AI semantic conventions. Set the GOOGLE_CLOUD_AGENT_ENGINE_ENABLE_TELEMETRY environment variable to export these metrics to Cloud Monitoring as user-defined metrics, alongside agent traces and logs.
