feature: Filter or add a visual cue for required settings in meltano config list #9043
Description
Feature scope
CLI (options, error messages, logging, etc.)
Description
The output of meltano config ... list can be pretty large, specially as SDK-based plugins gain more built-in settings.
As a user, it would be nice if it was easier to look at the output and know immediately which settings are required and which I can ignore when getting started with a plugin.
