Spyros Trigazis (strigazi) 9b1bd5da54 Add cluster upgrade to the API
To enable the rolling upgrade ability of Kubernetes Cluster, this
patch is proposing a new API /upgrade to support upgrade the
base operating system of nodes and the version of Kubernetes, even
add-ons running on the k8s cluster:

POST <ClusterID>/actions/upgrade

And the post body will be:

{
    "cluster_template": 'dd9cc5ed-3a2b-11e9-9233-fa163e46bcc2',
    "max_batch_size": 1,
    "nodegroup": "production_group"
}
