 the new command "config clone <identifier>" will make a deep copy of a
 branch of the configuration and will create a new configuration object at
 the same level. It can be used to clone loggers, datasources, subnets ...

 the command should not commit the config created.

 the command should print out the full path of the configuration object
 created

 Cloning an existing config part reduces the amount of manual typing
 required for new configurations.
