Announce PEP feature support for 'auto-subscribe' and 'filtered notifications'
Openfire supports PEP, which implies support for various Pubsub features. Openfire supports these features in its PEP implementation, but neglects to advertise this over Service Discovery.
Openfire's reponses to PEP node service discovery responses should include these features:
Filtered Notifications ("filtered-notifications")
Automatic Node Creation ("auto-create", already is advertised in existing code)
