Patch for fixing CPU throttling issues from CFS quotas

[tbarrella]

Hello, maybe this is something that will happen naturally at some point, but it's pretty desired, so I wanted to ask about it/track it...

What would you like to be added:
Applying the kernel patch discussed in kubernetes/kubernetes#67577 to EKS AMIs

Why is this needed:
To significantly improve performance for some workloads without having to disable CFS quotas (see the issue and patch)

Seems like the patch is now backported so we can use it by switching to v4.14.154, v4.19.84, or 5.4+.
