From the inverse of the conversion in MilliCPUToQuota: MinQuotaPeriod * MilliCPUToCPU / QuotaPeriod.

1000 microseconds is equivalent to 1ms defined here: https://github.com/torvalds/linux/blob/cac03ac368fabff0122853de2422d4e17a32de08/kernel/sched/core.c#L10546.

These limits are defined in the kernel: https://github.com/torvalds/linux/blob/0bddd227f3dc55975e2b8dfa7fc6f959b062a2c7/kernel/sched/sched.h#L427-L428.

100000 microseconds is equivalent to 100ms.

CgroupConfig holds the cgroup configuration information.
