use get_node_config().

jid -- The JID of the pubsub service.
node -- Optional name of the node to create. If no name is
provided, the server MAY generate a node ID for you.
The server can also assign a different name than the
one you provide; check the result stanza to see if
the server assigned a name.

to using 'leaf' if no type is provided.
