Gerhard Schlager 7c3a29c9d6 DEV: Add converter framework for migrations-tooling (#28540) ... * Updates GitHub Actions * Switches from `bundler/inline` to an optional group in the `Gemfile` because the previous solution didn't work well with rspec * Adds the converter framework and tests * Allows loading private converters (see README) * Switches from multiple CLI tools to a single CLI * Makes DB connections reusable and adds a new abstraction for the `IntermediateDB` * `IntermediateDB` acts as an interface for IPC calls when a converter steps runs in parallel (forks). Only the main process writes to the DB. * Includes a simple example implementation of a converter for now.		2024-09-09 17:14:39 +02:00
