Scaffold SwG module

This is a tracking issue for scaffolding out the SwG module foundation - essentially putting together all the “uncontroversial” pieces about adding a new module which don’t require much further design consideration since they rely on established infrastructure.

Do not alter or remove anything below. The following sections will be managed by moderators only.

Acceptance criteria

• There should be a new module subscribe-with-google.
• It should be entirely hidden behind an swgModule feature flag.
• The module info should be as follows:
  • Title: Subscribe with Google
  • Description: Generate revenue through your content by adding subscriptions or contributions to your publication
  • Order: 7
  • Homepage: _https://publishercenter.google.com/_
• It should have a settings implementation with ownership concept and the following settings:
  • publicationID: The publication ID to use.
  • products: The list of products available.
  • Both of these settings should affect module ownership.
• It should come with a JS file assets/js/googlesitekit-modules-subscribe-with-google.js which registers the module and its datastore in JS.
  • The datastore should for now be just a base module store with support for the two settings.

Implementation Brief

• Complete #3120.
• Specifically, introduce the swgModule feature flag and make sure the module is only loaded when that feature flag is enabled.

Test Coverage

• Add test coverage for the module class and dynamic JS components.
• Add Storybook coverage for the module setup UI and the module settings panel.

Visual Regression Changes

• N/A

QA Brief

• Enable the swgModule feature flag with the tester plugin
• Click “Set up Subscribe with Google” on the Settings > Connect More Services page
• Fill out the form, then click “Configure Subscribe with Google”
  • The Publication ID field expects a domain, such as example.com
  • The Products field expects a list of product names, one per line
  • You should see a congratulations message after submitting the form
• Edit the Subscribe with Google plugin’s settings
  • You should be able to update the Publication ID and Products fields

Changelog entry

• Scaffold Subscribe with Google module.

Thanks @ChrisAntaki!

@felixarntz, I ran another test with the latest develop and I see the Dashboard Visitor Widget error again. I can follow up on a separate ticket for this issue. Otherwise I think it’s safe to push this to approval.
