- [kubelet] Change default `cpuCFSQuotaPeriod` value with enabled `cpuCFSQuotaPeriod` flag from 100ms to 100µs to match the Linux CFS and k8s defaults. `cpuCFSQuotaPeriod` of 100ms now requires `customCPUCFSQuotaPeriod` flag to be set to work.

- A kubelet parameter and config option has been added to change the CFS quota period from the default 100ms to some other value between 1µs and 1s. This was done to improve response latencies for workloads running in clusters with guaranteed and burstable QoS classes.
