This PR adds the following changes
1. Refactor `microsoft/callbacks_controller` to move common logic to
`oauth_callback_controller`, most of the logic is re-used for Google
2. Add UI components, `googleClient` and I18n entries for Google login
3. Add Google callback and inbox creation
4. Add a `joinUrl` utility along with specs (need to move it to utils)
5. Add `GoogleConcern`, `Google::AuthorizationsController` and
`Google::CallbacksController`
> Note: The UI is hidden for now, so we can merge this without any
hiccups, to enable it just revert the commit `05c18de`
