Proposal & RoadMap: Extend cache runtime interface for full data lifecycle

[xliuqq]

Add Proposal & RoadMap for 'Extend cache runtime interface for full data lifecycle'.

The work tasks are described as follows：

• Curvine Integration：Implement working reference adapters for Curvine；
• DataOperation Support ：Implement DataOperation interface including DataLoad and DataOperation for cache runtime；
• In-Place upgrade and rebuild：Implement in-place upgrade for engine version update and in-place cache rebuild after node failure or config change.

@cheyang @Syspretor Please help review this. Thanks!

This API snippet seems internally inconsistent:Since this proposal is describing the interface contract, could we clean up this example first so it can be used as a reliable implementation reference?

rename it to "ExecutionEntries", these entries are executing at Runtime Master/Worker(if no Master) Pod to support out-of-tree integration for different cache systems.

Pull request overview

Adds a new proposal document describing how to extend Fluid’s generic CacheRuntime to support full data lifecycle management (Curvine integration, standardized DataOperation, and in-place upgrade/rebuild), along with supporting diagrams.

Changes:

• Add proposal markdown describing Curvine integration flow and required CacheRuntimeClass extensions.
• Propose a DataOperation capability model and runtime-side operator interfaces.
• Add lifecycle diagrams (state transform, in-place upgrade/rebuild flow, Curvine integration).
