This is an automated cherry-pick of #5786

/assign kolyshkin

NONE

Retry to set CPU load balancing before return the error
4d529c2 
It possible that the kernel will rebuild sched_domain related files and
because of it enabling or disabling CPU load balancing for container CPUs
will fail with different file errors:

1. lstat /proc/sys/kernel/sched_domain/cpu22/domain1/flags: no such file or directory
2. readdirent /proc/sys/kernel/sched_domain/cpu66/domain0: no such file or directory

Add retry logic around setting CPU load balancing values to reduce possibility of such errors.
