[Fix] Client in CLI uses correct transfer config (#747)

This fixes the issue that the cli uses the default transfer config. 

After ` skyplane config set azure_instance_class DCASv5`, run cp
command, found the following logs.
```
 23:40:45 [DEBUG] User confirmed transfer
23:40:45 [INFO]  [Provisioner.add_task] Queue ProvisionerTask(cloud_provider=‘azure’, region=‘eastus’, 
vm_type=‘Standard_D2_v5’, ...)
```

With the fix, the logs became
```
00:42:14 [DEBUG] User confirmed transfer
00:42:14 [INFO]  [Provisioner.add_task] Queue ProvisionerTask(cloud_provider='azure', region='eastus', 
vm_type='DCASv5', ...)
```
