prosodyctl shell: Move non-error result lines back to stdout, suppress with --quiet
We're figuring out how to keep usability and support machine-readability too.
We moved the status line (repl-result) to stderr so that when parsing
something like a table, it didn't get in the way. However sometimes the status
line is the thing we want to parse (e.g. invite creation). Parsing stderr
loses one of the purposes of stderr - to have an error-only channel to emit
stuff out of band (such as error messages).
So the new approach is:
- Status line on stdout, unless it's an error
- If you're parsing the output ("content") of the command, pass --quiet to
suppress the status line.
