The test case json files will increase in complexity with the move from
dnf to json. They quantity of them will also continue to grow as new
distros, architectures, boot methods, image types, and blueprint
customizations become available. The generate-test-cases script
simplifies the process of creating new test cases. It accepts a compose
request and boot method as input and then uses osbuild-pipeline,
osbuild, and image-info to generate the test case.
