Proposal: Monorepo for Fleetbase Extensions

[roncodes]

Currently considering combining extensions into a single repository. Currently backend and frontend for a single extension is split into their own proejct/repo. For example fleetops has two repo's fleetbase/fleetops-api and fleetbase/fleetops-engine - After this proposal fleetops would be available in a single fleetbase/fleetops repo.

The idea of combining repositories for a frontend and backend application into a single monorepo is not uncommon and has both advantages and disadvantages.

Advantages of a Monorepo

1. Unified Development Experience: Developers can pull one repository and have everything they need to work on a feature that may require changes in both frontend and backend.
2. Simplified CI/CD: Having a single repository can make CI/CD pipelines easier to manage and configure.
3. Atomic Commits: You can update the frontend and backend in one commit, ensuring consistency.
4. Shared Resources: Easier to share common configurations, libraries, and modules.
5. Dependency Management: Easier to manage cross-project dependencies.

Disadvantages of a Monorepo

1. Learning Curve: Developers need to understand both frontend and backend project structures and how they interact.
2. Build Complexity: It may be more complicated to only build/test/deploy what has changed.
3. Large Repository: Over time, the repository may grow large, and cloning or pulling changes may become slower.
4. Tooling: Not all package managers and build tools play nicely with a monorepo structure.

While I do believe the advantages far outweigh the disadvantages I wanted to share this proposal for feedback.

Here is an example of the new extension monorepo structure.
