[Features] support component-level stop and start capabilities

What is the user interaction of your feature

The StarRocks kernel supports multi-warehouse functionality, allowing CN (Compute Node) instances to be grouped into different warehouses. This setup enables physical isolation of compute resources. When using KB to manage these, we can consider mapping one warehouse to one KB component. During cluster operation, it may be necessary to dynamically add or remove warehouses (components).

Additionally, the warehouse(component) can be stopped and started independently. However, the OpsRequest only supports cluster-level stop and start operations. To enhance operational flexibility and granular control, it's necessary to support component-level stop and start capabilities.
