Recreate cluster nodes
During the upgrade process it tears down all existing VM's and assigns new VHD/Tags etc.
But this process seems to be only available for az aks upgrade, what i would like to be able to do is to refresh all the vms and not rely on manually deleting to purge them out of the cluster.
az aks upgrade -vm
It skips the cluster upgrade without changing anything and just gets the latest VHD assignments and aks engine numbers.
The background is, that i scaled the cluster to 5 Nodes and 4 were on aks 0.35 and the node0 was on 0.33.4 which could cause problems no?

This is done for the aks engine and I wanted to give more clarification I would like the --force option to recreate all VMS.
i.e. az aks upgrade -k 1.13.5 -g mygroup -n mycluster --force
It would recreate all VM's even though the cluster is already on 1.13.5
