CLI tooling to inspect bundles

[tsandall]

Bundles are pretty simple. We can summarize their structure and contents as follows:

• They are gzipped tarballs
• They can contain .rego files in any location
• They can contain data.json and data.yaml files that are mounted into data based on their directory path
• They can contain a .manifest file with various metadata bits
• They can contain policy.wasm files that are mounted into data based on "resolver" configuration in the manifest
• They can contain a signatures.json file with cryptographic signatures on the files above

At the same time, to inspect them, users have to run various unix commands like tar, cat, ls, etc. It would be nice to have a subcommand in opa that could print a description of the bundle for debugging purposes. Specifically, it be nice to see a summary of the packages that are contributed by .rego files in bundle as well as the data locations defined by the data.json, etc. files.

It could also be nice to have the tooling support comparisons on bundles.

Hey, Is there a rough timeline for this work in progress?

This task is actively being worked on. It should land in the next couple of releases.
