Using Cloud Select to choose an Instance Type

Cloud select https://github.com/converged-computing/cloud-select is a tool that makes it easy to query cached cloud prices, currently supported for instances. In this quick demo we show using it in Playground https://github.com/converged-computing/playground to select an instance type. Playground works by way of having a tutorial repository deploy its own metadata (e.g., cpus/memory needed) and containers, and then being able to deploy as follows:

$ playground deploy --backend aws github.com/rse-ops/flux-tutorials radiuss-aws-2022

Thus, when we combine the two, we can get the list of cheapest instances that match the request and ask the user to choose, fall back to a default, or exit and start over.
