During testing, noticed the following error in the log

INFO 2024-03-14T21:44:02.993719249Z [resource.labels.containerName: nginx-gateway] Trace[255962658]: "DeltaFIFO Pop Process" ID:gatewayclasses.gateway.networking.k8s.io,Depth:26,Reason:slow event handlers blocking the queue (14-Mar-2024 21:44:02.846) (total time: 143ms):

Error comes from https://github.com/kubernetes/client-go/blob/1518fca9f06c6a73fc091535b8966c71704e657b/tools/cache/delta_fifo.go#L600 Not related to product telemetry feature.

Further investigation is needed to see if any fix is needed.

Additionally, it be nice if such errors are logged using our structured logger https://github.com/nginxinc/nginx-gateway-fabric/issues/1101

How often does this occur? Is there any impact on the performance of NGF?
