Eren Başak bbc2a0c489 Kubernetes Cluster and Nodepool Upgrades ...

This patch implements the upgrade logic for kubernetes clusters.

Upgrade is done sequentially, node-by-node, in the order of create time.
Upgrade operation starts with the CP nodes. After all CP nodes are upgraded, then
moves to worker nodes.

For upgrading a node, it creates a new node with upgraded version of k8s, adds it to
the cluster and draing & removes the corresponding old node. There's no actual relation
between the old node and new node in reality.
