This commit combines two related changes to implement cross compute group
peer read routing and optimize the peer cache I/O path. Changes:
1. Cross Compute Group Peer Read Routing:
- Implement peer read routing across different compute groups to enable data
sharing between groups
- Add routing logic to select optimal peer nodes for cache reads
- Support cross-group tablet peer discovery and selection
2. Peer Cache I/O Path Optimization:
- Optimize peer cache server path using IOBuf attachment for zero-copy data
transfer
- Reduce memory copies in the peer cache read path by leveraging bRPC IOBuf
attachment mechanism
- Improve peer cache read performance and reduce memory overhead (#8899)
