Daniel Safta a046a7a650 Add kubernetes 1.22.5 pkg 
Here are the changes needed for adding k8s v1.22.5
in StarlingX alongside with the changes needed
for the build environment to find and build the package.

The package builds successfully.
Deployed an iso with k8s 1.22.5 on
AIO-SX and AIO-DX. The deployment phase
works and the pods are up and running after
the upgrade completes.

Subject: [PATCH 5/7] 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.
