Workload partitioning wrong CRI-O configuration key. The doc said that CRI-O workload partition configuration keys are `cpushares` and `CPUs` but it looks like the `CPUs` is incorrect and the correct key is `cpuset`.

We need to replace the `CPUs` with `cpuset` as follows:

[crio.runtime.workloads.management]
activation_annotation = "target.workload.openshift.io/management"
annotation_prefix = "resources.workload.openshift.io"
[crio.runtime.workloads.management.resources]
cpushares = 0
cpuset = "0-1, 52-53"
