Zane Bitter cfff39ce68 Always cache attributes in outputs in Resource.node_data()
Ensure that attributes that are referenced in outputs get cached (and
therefore stored in the database) even when they are not referenced by
other resources.

features:
- Resource attributes are now stored at the time a resource is created or
updated, allowing for fast resolution of outputs without having to retrieve
live data from the underlying physical resource. To minimise compatibility
problems, the behaviour of the `show` attribute, the `with_attr` option to
the resource show API, and stacks that do not yet use the convergence
architecture (due to the convergence_engine being disabled at the time they
were created) is unchanged - in each of these cases live data will still be
returned.
