Provide --format=JSON for debug:container and other debug commands

[ console ] The original symfony/console package allows output in JSON format.

Problem/Motivation

There are some extensions that rely on the output of drupal debug:container --format=JSON, which we currently cannot get with the drupal console. Parsing a JSON response is 10x easier than parsing multiline table output.

Details to include:

• See above.

How to reproduce

drupal debug:container

Details to include:

• Drupal version (you can obtain this by running drupal site:status). 8.8.8
• Console version (you can obtain this by running composer show | grep drupal/console). 1.9
• Console Launcher version (you can obtain this by running outside of a drupal site drupal --version).
• Steps to reproduce
  • Create a new symfony/symfony-standard project
  • Run console debug:container --format=JSON

Solution

Use the same formatters the symfony/console project uses.
