Make it easier to output JSON

[rbren]

Is your feature request related to a problem? Please describe.
If I want to output JSON, I seem to have to set --output-file. There's no way to output JSON to stdout, or non-json to a file

Describe the solution you'd like
Have separate --output-file and --format flags

Describe alternatives you've considered
Better documentation of existing behavior
