support low-priority VMs
Azure Databricks and low-priority VMs are a great match. Their use cases overlap heavily: https://docs.microsoft.com/en-us/azure/batch/batch-low-pri-vms#use-cases-for-low-priority-vms.

Or even a simple way to hand off to Low pri VMs. This is achievable to some extent currently using the Azure ML SDK.
This is a great idea.
