For tools, --quiet has ambiguous behavior, since tools cannot manage output logged by shared server code.

This should not cause corruption, as far as we know, since all logged messages will be redirected to stderr in the case where data is written to stdout.

> mongoexport --db test --collection test --dbpath /data/db --quiet --out output.json

expect no output to stdout or stderr, instead see in stdout:
