* Remove Azure kube-up as the Azure community has focused efforts elsewhere. ([#41672](https://github.com/kubernetes/kubernetes/pull/41672), [@mikedanese](https://github.com/mikedanese))

a low OOM Score. 
  
  As of now both `system-node-critical` and `system-cluster-critical` pods have -997 OOM score, making them one of the last processes to be OOMKilled. By definition `system-cluster-critical` pods can be scheduled elsewhere if there is a resource crunch on the node where as `system-node-critical` pods cannot be rescheduled. This was the reason for `system-node-critical` to have higher priority value than `system-cluster-critical`.  This change allows only `system-node-critical`...
