|| `--auto-upgrade` | Sets auto upgrade maintenance policy.
Policy defines if Node Group can be upgraded to newer version revision in specified maintenance window.
Auto upgrade is 'graceful': new nodes are created, while old nodes drained by one. Please setup Pod Disruption Budget, for graceful pods drain.
For details about PDB see https://kubernetes.io/docs/tasks/run-application/configure-pdb/
New revision contains can contain bug and security fixes, so it's recommended to leave this policy enabled. Node Group never upgraded to another major version automatically, even with this policy set to true.
