Waited for 1.194912169s due to client-side throttling, not priority and fairness

Hello there,

I am using Kong in K8S and the Kong Proxy is version 2.6.0 and the Kong Ingress controller is 2.0.6. We have multiple tenants and each tenant have around 20 ingress files each for kong. So far, we have a total of 225 ingress files for our tenants and there will be a lot more to come. When I apply the ingress files, the ingress controller logs contains these messages:

I0208 15:22:33.413408       1 request.go:665] Waited for 1.198085452s due to client-side throttling, not priority and fairness, request: GET:https://url:443/apis/networking.k8s.io/v1/namespaces/namespacename/ingresses/ingressname

These messages appears at 10 seconds interval and then stop showing up after 10 minutes. Any idea what this could be?
