Fixes for SmartOS datasource

1. fixed conflation of user-data and cloud-init user-data. Cloud-init
   user-data is now namespaced as 'cloud-init:user-data'.
2. user-scripts (not user-data) are now fetched from the meta-data service
   each boot and executed as in the scripts directory
3. datacenter name is now namespaced as sdc:datacenter
4. user-scripts will now have '#!/bin/bash' magically prepended
   if the 'file' thinks its plain text and it does not start with '#!'
