feat: Add orchestration models and services for Kubernetes cluster management

- Implemented Pydantic models for Kubernetes cluster state representation in `cluster.py`.
- Created a `Resource` class for converting JSON/dict to Python objects in `resource.py`.
- Established user models and services for user management, including password hashing and JWT token generation.
- Developed application orchestration services for managing Kubernetes applications, including installation and uninstallation.
- Added cluster service for retrieving cluster status and health reports.
- Introduced node service for fetching node resource details and health status.
- Implemented user service for handling user authentication and management.
