Code Issues Proposed changes

Set kube-cpu-mgr-policy default to static

Browse Source 
In kernel 6.6, when kube-cpu-mgr-policy is none, all pods in
default namespace are getting affined to platform cores even
restricting all application pods to run on platform cores.

Setting kube-cpu-mgr-policy default to static will fix the issue

Note: The none policy explicitly enables the existing default CPU
      affinity scheme, providing no affinity beyond what the OS
      scheduler does automatically.

Test Plan:
PASS: Install an iso as AIO-SX, create a pod , verify that it is affined
      application cores.
PASS: Verify all pods in kube-system namespace are affined to platform
      cores
