spot property
Whether the nodes are created as Spot VM instances (https://cloud.google.com/compute/docs/instances/spot).
Spot VMs are the latest update to legacy preemptible VMs. Spot VMs do not have a maximum lifetime. Legacy and Spot preemptible nodes cannot be used in a node pool with the CONTROLLER role or in the DEFAULT node pool if the CONTROLLER role is not assigned (the DEFAULT node pool will assume the CONTROLLER role).
Optional.
Implementation
