Add DataClean CRD for cache management

This commit introduces a new DataClean CRD that allows users to clean
dataset cache on demand, complementing the existing DataLoad feature.

Changes:
- Add DataClean CRD definition with target dataset and TTL support
- Implement controller to handle cache cleaning lifecycle
- Support both Alluxio and Jindo runtimes
- Integrate with existing CleanCache operations
