* Add `worker_price` to allow worker spot instances. Defaults to empty string for the worker autoscaling group to use regular on-demand instances. * Add `spot_price` to internal `workers` module for spot worker pools * Note: Unlike GCP `preemptible` workers, spot instances require you to pick a bid price.
