Sachin Gopala Krishna d0e346c423 Debian: Add kubernetes 1.24.4 remaining patches 
This ports the remaining kubernetes 1.24.4 patches.

The following patches were refactored slightly to allow for
upstream changes:
kubelet-cpumanager-disable-CFS-quota-throttling-for-.patch
kubelet-cpumanager-keep-normal-containers-off-reserv.patch

The following patch was added to get tests working again:
cpumanager-policy-static-test-refactor.patch

Test-plan:

1. Revert-use-subpath-for-coredns-only-for-default-repo:
   Kubeadm commands worked as expected

2. enable-support-for-kubernetes-to-ignore-isolcpus:
   Set kube-cpu-mgr-policy as static and allocated some isolcpus.
   i.  Deployed a pod with dedicated CPU and verified that it is not
       affined to isolcpus.
   ii. kube-ignore-isol-cpus is set to enabled, deployed a pod with
       dedicated CPU and verified that is allocated to isolated CPU.

3. kubeadm-create-platform-pods-with-zero-CPU-resources:
   Verified the usage of CPUs is 0 in coredns, kube-controller-manager,
   kube-scheduler, and kube-apiserver pods of kube-system namespace.

4. kubelet-cpumanager-disable-CFS-quota-throttling-for- :
   Verified that pods that in the "Guaranteed" QoS class, on hosts that
   have "kube-cpu-mgr-policy=static" have cpu.cfs_quota_us set to -1.

5. kubelet-cpumanager-infra-pods-use-system-reserved-CP:
   Verified that platform pods are affined to platform CPUs

6. kubelet-cpumanager-introduce-concept-of-isolated-CPU:
   Verified pods can allocate isolated CPUs and are affined to them.
   Verified pods allocating application CPUs don't get isolated CPUs.
   Verified that pods allocating dedicated and isolated CPUs are affined
   to the dedicated CPUs.
   Verified that pods allocating non-dedicated and isolated CPUs are
   affined to the isolated CPUs.

7. kubelet-cpumanager-keep-normal-containers-off-reserv:
   Verified the pod which is not in platform namespace are affined to
   application or application isolated CPUs

8. kubelet-sort-isolcpus-allocation-when-SMT-enabled:
   Verified after enabling SMT multithreading that isolated CPUs are
   allocated as lowest-numbered SMT siblings first and then
   higher-numbered SMT siblings, then any single thread.

9. kubernetes-make-isolcpus-allocation-SMT-aware:
   Verified after enabling SMT multithreading that isolated CPUs are
   allocated as pairs of SMT siblings first, then already-existing
   single SMT siblings, then we allocate one of a pair of SMT siblings
   as a last resort.

CPUs and reserved CPUs.
