Dmitry Verkhoturov d0f9e6dc36 clarify CPUCFSQuotaPeriod values, set the minimum to 1ms
cpu.cfs_period_us is measured in microseconds in the kernel but
provided in time.Duration by the user, that change clarifies the code
to make this evident to the reader.

Also, the minimum value for that feature is 1ms and not 1μs, and this
change alters the validation to reject values smaller than 1ms.
