(PDB-822) Change acceptance tests to incorporate structured facts.

This patch augments our basic_fact_retrieval and import_export acceptance tests
to include structured facts, and also bumps the version of the nodes query in
the facts/find indirector so structured facts are returned when puppet facts
find is issued to the PDB terminus.
It affects more then facts find, it also affects the inventory HTTP service that the console currently uses. Can you show me the output of facts find with this patch? Do you have something handy?
