AKS-related scripts

• aksdebug *nodename* to be able to exec into an AKS node (unlocking Metricbeat, for example)
• aksnode *cluster* *resourcegroup* to see nodepools' Kubernetes version
• aksnodeupg *cluster* *resourcegroup* *newkubeversion* *nodepoolname* upgrade a nodepool to new Kubernetes version
• getevents *nodepoolname* continuous flow of Kubernetes events related to a specific nodepool
• watch getnodepool *nodepoolname* displays nodepool's hosts' state every 2 seconds
• watch podsnotrunning *nodepoolname* displays not ready Pods on nodepool every 2 seconds
