- 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))

// Reject new lock requests immediately when this many are queued
// for the local lock mutex.
// We do not block unlocking or maintenance, but they add to the count.
// The limit is set to allow for bursty behavior,
// but prevent requests to overload the server completely.
// Rejected clients are expected to retry.
