This adds additional cpu features:
- pstate status from status of intel_pstate driver
- pstate scaling settings from scaling_governor
- cstate enable from max_cstates in intel_idle driver
Some workloads may benefit from Intel Turbo Boost technology being
disabled. This patch sets the
'feature.node.kubernetes.io/cpu-pstate.turbo' label to 'false' if we can
detect that it has been disabled. If detection fails no label is
published.
Remove 'cpuid', 'pstate' and 'rdt' feature sources and move their
functionality under the 'cpu' source. The goal is to have a more
systematic organization of feature sources and labels. After this change
we now basically have one source per type of hw, one for kernel and one
for userspace sw.
Related feature labels are changed, correspondingly, new labels being:
feature.node.k8s.io/cpu-cpuid.<cpuid flag>
feature.node.k8s.io/cpu-pstate.turbo
feature.node.k8s.io/cpu-rdt.<rdt feature>
