what

Update kops-private-topology.yaml.gotmpl to include optional settings for kublet.cpuCFSQuotaPeriod and kublet.cpuCFSQuota

why

Due to a pair of bugs in the Linux kernel, the default cpuCFSQuotaPeriod of 100ms leads to many kinds of workloads being improperly throttled. Setting cpuCFSQuotaPeriod to a smaller duration (recommended: 5ms to 20ms) can greatly reduce the impact of these bugs.
