enhance: Implement rewatch mechanism for etcd failure scenarios (#43829) 
issue: #43828
Implement robust rewatch mechanism to handle etcd connection failures
and node reconnection scenarios in DataCoord and QueryCoord, along with
heartbeat lag monitoring capabilities.

Changes include:
- Implement rewatchDataNodes/rewatchQueryNodes callbacks for etcd
reconnection scenarios
- Add idempotent rewatchNodes method to handle etcd session recovery
gracefully
- Add QueryCoordLastHeartbeatTimeStamp metric for monitoring node
heartbeat lag
- Clean up heartbeat metrics when nodes go down to prevent metric leaks
