Boovan Rajendran 96d5a7a4dd Add kubernetes 1.27.5 patches 
This change ports the following kubernetes 1.27.5 patches which were
refactored slightly to allow for upstream changes

The following patches were applied cleanly:
kubeadm-create-platform-pods-with-zero-CPU-resources.patch
kubelet-sort-isolcpus-allocation-when-SMT-enabled.patch

The following patches were refactored:
Revert-use-subpath-for-coredns-only-for-default-repo.patch
kubernetes-make-isolcpus-allocation-SMT-aware.patch
kubelet-cpumanager-disable-CFS-quota-throttling.patch
kubelet-cpumanager-keep-normal-containers-off-reserv.patch
kubelet-cpumanager-infra-pods-use-system-reserved-CP.patch
kubelet-cpumanager-introduce-concept-of-isolated-CPU.patch
enable-support-for-kubernetes-to-ignore-isolcpus.patch
kubelet-CFS-quota-throttling-for-non-integer-cpulimit.patch

Test Plan:
PASS: Kubernetes package 1.27.5 builds properly.
PASS: Run all Kubelet, kubeadm, kubectl make tests for affected code.

Subject: [PATCH] kubeadm: create platform pods with zero CPU resources
We want to specify zero CPU resources when creating the manifests
for the static platform pods, as a workaround for the lack of
separate resource tracking for platform resources.
We also specify zero CPU resources for the coredns deployment.
manifests.go appears to be the main file for this, not sure if the
others are used but I changed them just in case.
