Enhance Cloudly Configuration and Testing Setup

- Updated README to include architecture overview and details on components.
- Changed import paths in test helpers and test files to use the new Git zone packages.
- Modified S3 bucket name in test setup for consistency.
- Updated CloudlyConfig class to use more descriptive environment variable names for MongoDB and S3 configuration.
- Adjusted ImageManager to retrieve the S3 bucket name from the configuration instead of hardcoding it.
