How we are closing the gap on replicating *everything* in GitLab Geo

What this post added

Introduced a new Geo replication and verification framework to reduce code duplication and enable easier addition of new data types. This involved designing a `Replicator` class and `Replicator strategies` for blobs and Git repositories. Implemented initial support for replicating new Package files as a proof of concept, laying the foundation for future data type replication and verification.
