100% trace sampling causes performance degradation

How to detect:
When tracing is enabled in Envoy Gateway, all requests are traced at 100% sample rate by default, which may cause performance issues in high-traffic production environments.
Recommended action:
Evaluate whether full tracing is necessary for your use case. Consider disabling tracing in high-traffic production environments, or refer to EnvoyProxy documentation for configuring a lower sample rate. Tracing is controlled via the telemetry.tracing field in the EnvoyProxy CRD.
