Subscription authorization
Subscription authorization

Since the introduction of Event Type Authorization, it was planned that
Subscriptions would also be authorized. Even though data is already
protected through Event Type Authorization, users can still accidentally
commit offsets to subscriptions owned by other users, eventually causing
applications to not process all the data. Subscription could also be
accidentally deleted or have it's slots assigned to some other
application.

With this feature we address all of the problems above. This is just the
API definition.
