Changing this forces a new resource to be created. When setting `priority` to Spot - you must configure an `eviction_policy`, `spot_max_price` and add the applicable `node_labels` and `node_taints` [as per the Azure Documentation](https://docs.microsoft.com/azure/aks/spot-node-pool).

Valid values are `-1` (the current on-demand price for a Virtual Machine) or a positive value with up to five decimal places. Changing this forces a new resource to be created. This field can only be configured when `priority` is set to `Spot`.
