feat: Add Dockerfile and custom package for minimal Cube.js setup

- Introduced a new custom-package.json for managing dependencies.
- Created a Dockerfile.minimal for building a lightweight Cube.js server image with Oracle and Postgres drivers.
- Configured build and runtime environments, including necessary system dependencies and symlinks for CLI tools.
