+Subject: [PATCH] Add args file to support huge configurations
+
+The command line has a length limitation, which restricts the number of configurations it can support. To overcome this limitation, introduce a new argument: arg_file. Users can place extensive configurations within the arg_file, enabling the GNMI client to handle a larger and more complex set of configurations.
