feat: add support for quiet ps:scale output

The previous output required too much parsing to be used in an automated fashion. This change makes that a bit easier, without sacrificing usability.

Note that the output is quite a bit different from heroku. This is purposeful as we do not have the concept of dynos.

Closes #3520
