 Core:
    - Support singletons (see types/issue for a good reason)
+      - probably name them only_once and use that as the internal id!
    - extend cdist_tree_wrapper to look for optional/mandority parameters for types
       - gives "good" database, which contains only valid objects
    - use ssh with master socket?
