Reshape Idavoll as a PubSubResource.
PubSubResource is Wokkel's newer interface for building (parts of) XMPP
publish-subscribe services and replaces the old interface of PubSubService. It
is more flexible for adding new protocol, allows for node-as-code (providing a
specific backend per node), and permits accepting requests for different
entities (virtual hosts or PEP-like settings).
This moves over the current backend to use the new interface, so new code for
previously unsupported protocol can be added down the line.
