Dependency ownership: Unused renovate rules

[legrego]

Our dependency management CLI allows us to find dependencies without owners (#196767). In order to keep our renovate.json file as tidy as possible, we should also support looking in the other direction.

Note

Script names, flags, options, and syntaxes below are for illustrative purposes only. You are free to develop these as you see fit.

Script to identify unused renovate rules

A script should exist which generates a list of renovate rules which reference dependencies that do not exist in Kibana's package.json.

node scripts/dependency_ownership.js --find-unused-rules

The script should output its result in JSON format.

Script to remove unused renovate rules

A script should exist which removes renovate rules which reference dependencies that do not exist in Kibana's package.json.

node scripts/dependency_ownership.js --remove-unused-rules

The script should output a summary of the actions taken.
