Sync `deployment` to replica cluster

if we deploy a new SQL to OpenMLDB, it will not sync to replica cluster currently.

The issue mentions that a new SQL deployment does not sync to a replica cluster. Look for deployment-related code and replication logic in the OpenMLDB source. Start by searching for 'deployment' and 'replica' in the codebase to understand the current sync mechanism. Determine what 'sync' entails—whether it's data, schema, or configuration—and identify where the deployment command is handled versus where replication occurs.
