TACACS+ Authorization Command & Arguments Boundary

Each TACACS+ authorization entry on an ACLI command line comprises the command and its arguments. Currently everything typed as a TACACS+ authorization command by an authenticated admin user, including the arguments, is sent to the TACACS+ server in the command field of the TACACS+ message; the argument field in the TACACS+ message contains no arguments and is set to “cmd-arg=<CR>”. This feature adds the new parameter tacacs-authorization-arg-mode to the authentication configuration element, which enables the TACACS+ authorization command and its arguments to be sent to the TACACS+ server separately.
