Jim Gauld 229ecb0d99 Add staged versions of kubernetes 1.18.1 and 1.19.13
Multiple versions of kubernetes are required to support upgrade.

This adds staged versions of kubernetes 1.18.1 and 1.19.13, each are
built with a specific version of golang.

All subpackage versions are included in the iso image without collisions.

The following patches are included upstream in kubernetes 1.19 and are no
longer required:
Patch1: 0001-Fix-pagesize-check-to-allow-for-options-already-endi.patch
Patch3: fix_http2_erringroundtripper_handling.patch
Patch8: Fix-exclusive-CPU-allocations-being-deleted-at-conta.patch

The following patches are ported to specific kubernetes version:
kubelet-cpumanager-disable-CFS-quota-throttling-for-.patch
kubelet-cpumanager-keep-normal-containers-off-reserv.patch
kubelet-cpumanager-infrastructure-pods-use-system-re.patch
kubelet-cpumanager-introduce-concept-of-isolated-CPU.patch
kubeadm-create-platform-pods-with-zero-CPU-resources.patch
enable-support-for-kubernetes-to-ignore-isolcpus.patch

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 by I changed them just in case.
