Simplify federation and oauth token callbacks

The token provider listened for specific callbacks from the
federation and oauth APIs. These were mainly for token invalidation
and token persistence removal. Now that the sql token driver and uuid
token provider have been removed, we can remove the need for
persistence notifications.

Instead, both of these cases can use a generic token cache
invalidation callback. This makes the token provider Manager simpler
because it only has to listen for a single internal notification to
invalidate the token cache, instead of multiple. It also makes the
code sending the notification easier to understand because it's
clearer about what it's doing.
