    AttributeError: 'NSOClient' object has no attribute 'get_datastore_data'
ERROR: Minions returned with non-zero exit code

Start with salt/proxy/cisconso.py at get_data and the traceback's call to client.get_datastore_data; compare that client method with the available NSOClient methods mentioned in the report. Reproduce the cisconso.get_data command against a running proxy and confirm it returns the device configuration without the AttributeError.
