I have written several similar programs using Python's cmd.Cmd class. Command completion, help messages, etc are all taken care of. All I need to do is to write the nitty gritty for each command and copious log the actions taken their return status to catch any networking, REST, etc issues. It is even possible to nest command interpreters within command interpreters to create sub-commands if applicable. I should mention that I am more productive in Python than either Java or Go - so this may taint my view of alternatives.
