Outputs

• Would be nice to have a less indented JSON output (not 8 chars but 2 or 4)
• Would be nice to have a plain text output that's easier for scripting (or yaml)

Hi. I've made few changes to allow plain text output as an option for subcommands that already support the --output flag. I can also work on a less indented JSON output (or yaml) formatting as separate PRs if ok.
