I deploy the Wasme Operator according to this doc，but i found that there are many repeated log of pod wasme-cache-nbkx5.

[root@mesh-10-20-11-190 wasme]# kubectl get pods -n wasme
NAME                              READY   STATUS    RESTARTS   AGE
wasme-cache-nbkx5                 1/1     Running   0          51m
wasme-operator-59cfd7674d-msmsv   1/1     Running   0          50m

the output like

I suggest not to output these duplicate logs (approximately once every two seconds). These logs are not really important to us. The important ones are update logs, error logs, etc.
