New CLI command: rubocop --todo-to-done

[jtannas]

What does it do?

Autocorrect entries from a .rubocop_todo.yml one at a time, committing each to git as it goes.

Why do I want it?

Mass running Rubocop autocorrections on a legacy codebase in a way that makes it much easier to debug using git bisect and to git revert if something either goes wrong or goes against the tastes of the team.

How does it work:
