change CPUCFSQuotaPeriod default value to 100us to match Linux default
change CPUCFSQuotaPeriod default value to 100us to match Linux default

cpu.cfs_period_us is 100μs by default despite having an "ms" unit
for some unfortunate reason. Documentation:
https://www.kernel.org/doc/html/latest/scheduler/sched-bwc.html#management

The desired effect of that change is to match
k8s default `CPUCFSQuotaPeriod` value (100ms before that change)
with one used in k8s without the `CustomCPUCFSQuotaPeriod` flag enabled
and Linux CFS (100us, 1000x smaller than 100ms).
