Prefect serverless work pool executor

[TomNicholas]

One of Matt Rocklin's blog posts mentions Prefect's "serverless work pool"

My (hazy) understanding of what this is is a way to deploy a cluster in the cloud on-demand and submit work to it without having a client process controlling it at all times. This seems like it could be useful as a way to provision a cluster on which to run an in-memory rechunk without having to worry about turning off the cluster again.
