[Devel] [PATCH VZ9] configs: Enable PSI pressure monitoring by default for cgroup v2

[Konstantin Khorenko]

As we really want our product(s) are able to run on stock kernels, it’s much better to enable PSI via 
kernel boot option rather than recompile the kernel.
This way will work for stock kernel as well.

=> i will not apply kernel patch, please, file a task and use kernel boot option.
