MailingGroup API - Tighten up deprecations

The `MailingGroup.php` includes some very different APIs, e.g.
 * Several 'event'(subscribue/resubscribe) APIs
 * Some CRUD APIs for mailing data

The deprecation applies to the 'event' (subscribe/resubscribe) APIs --
because those can be done another way.  However, the CRUD for `MailingGroup`
records is the only way to do access that data.
