Initial support for cubbystack_config type/provider.
Modified deps.sh script
This commit modified Glance and Nova

There was information missing from the example Glance
configuration.

Network information was added to the example Nova configuration.
Additionally, network creation was removed from nova::network. It
should now be done outside of cubbystack. See the example manifests
for an example.

TODO: detail example configuration more. Possibly a cookbook.
Restructured examples
