Subject: [PATCH] Remove support for ignoring k8s isolated CPUs in sysinv

As we no longer have any users for this feature, we remove
support for ignoring isolated CPUs. This change removes code
that supports this feature in sysinv.

Test Plan:
AIO-SX:
PASS: Manually create /etc/kubernetes/ignore_isolcpus,
      assign host label 'kube-ignore-isol-cpus=enabled',
      yet a test pod is allocated to the application-isolated
      CPUs.

Story: 2010878
Task: 49571
