 Feature request from BIND 10 training in Amsterdam, August 2013:

 a version number (and date) field for the global BIND 10 config

 this could be used:
 * by admins to check for a specific change
 * by a change management system (future module)
 * by bindctl or other management tools to check if the service side config
 has been changed (to prevent race conditions when doing concurrent changes
 from different bindctls)
