This is part of the work described by #7156. Remove "unbuffered subscriptions" from the pubsub service. Replace them with a dedicated blocking "observer" mechanism. Use the observer mechanism for indexing. Add a SubscribeWithArgs method and deprecate the old Subscribe method. Remove SubscribeUnbuffered entirely (breaking). Rework the Subscription interface to eliminate exposed channels. Subscriptions now use a context to manage lifecycle notifications. Internalize the eventbus package.
