Tools do not copy over JSON metadata file

[shatterednirvana]

Right now the tools write both a YAML and JSON file that contain metadata about the cloud deployment, and should be copying these files to the head node in AppScale. We do copy the YAML file, but don't copy the JSON file, so we should copy it as well. Not copying the JSON file means that when the user tries to upload an app via the web UI, they get this error:
