MinIO server allows to throttle incoming requests:

- limit the number of active requests allowed across the cluster
- limit the wait duration for each request in the queue

These values are enabled using server's configuration or environment variables.

- Kubemark: added two flags, `--kube-api-qps` which indicates the maximum QPS to the apiserver, and `--kube-api-burst` which indicates maximum burst for throttle to the apiserver. ([#124147](https://github.com/kubernetes/kubernetes/pull/124147), [@devincd](https://github.com/devincd))
