Comment 1 for bug 1571976

For inconsistent result formats, I think we can unify them into the format which displayed when using --all option.

For adding "--more" option in command output list, I think we do not need to do this for now. The reasons are:
1. The output list api just returned the key and description:
RESP BODY: {"outputs": [{"output_key": "status_code", "description": "No description given"}, {"output_key": "result", "description": "No description given"}, {"output_key": "stderr", "description": "No description given"}, {"output_key": "stdout", "description": "No description given"}]}
2. Users can use show command to see the value.
