### Description of PR
With using cgroup v1, cpu.cfs_period_us control gets the default value of
100 000 when a new cgroup is created, but when YARN calculates the limit, it
uses 1 000 000 for that. Because of this we need to update cpu.cfs_period_us
before cpu.cfs_quota_us, to keep the ratio between the two values and not to
exceed the limit defined at parent level.
### How was this patch tested?
