[AMORO-3440] Implement the refresh and exploration of OptimizingGroup…

[mansonliwh]

Why are the changes needed?

Close #3440 .

Brief change log

The OptimizingService and OptimizerManager have been decoupled: the OptimizerManager handles metadata persistence and modifications, while the OptimizingService includes a watcher to synchronize the in-memory OptimizingQueue map with persisted data.
This allows the master node to run the OptimizingService while other nodes modify metadata via a web interface, ensuring the master stays updated.
