1) No zone defined. The object will only be synced in the local zone for HA purposes.
2) Zone is set to 'master'. Only nodes in the master zone will get this object and updates synced.
3) Zone is set to 'satellite'. Only nodes in the satellite zone, or in parent zones above will get this object and updates synced.
4) Zone is set to 'client'. Only nodes in the client zone, and in parent zones (satellite, master) will get object updates.
Furthermore this commit adds a bit more security measures for syncing object
config bottom-up which is clearly restricted at this time. Clients cannot
send their config to the top, but yet we only support the top-down thing we
also have with the cluster file config sync.
The initial sync will also take the zone relation model into account
and only allow object syncs only when the same conditions apply as written
above.

This is fairly ugly and sets an extension for the ConfigObjectUtility
delete handler to signal the OnActiveChanged handler inside the cluster
configsync to send a delete event to the other nodes.
