There were a few changes needed: * Plugins are now specified through `plugin:` config keyword. * All plugin gems need to be specified explicitly in Gemfile since they are no longer dependencies of plugins already specified explicitly. * All plugin gems need to be updated in other to use the new APIs. * One cop was renamed. * New offenses safe to correct were corrected directly with `bundle exec rubocop -a`. * New offenses unsafe to correct were added to the TODO configuration with `bundle exec rubocop --auto-gen-config --auto-gen-only-exclude --exclude-limit 1400 --no-auto-gen-timestamp`.
