    No longer index nodes by their name but by their UUID in the cluster
    config. This change changes large parts of the code, as the following
    adjustments were necessary:
     * Change the index key to UUID in the configuration and the
       ConfigWriter, including all methods.
     * Change all cross-references to nodes to use UUID's.
     * External interfaces (command line interface, IAllocator interface,
       hook scripts, etc.) are kept stable.
     * RPC-calls can resolve UUID's as target node arguments, if the RPC
       runner is based on a ConfigWriter instance. The result dictionary is
       presented in the form the nodes are addressed: by UUID if UUID's were
       given, or by name if names were given.
     * Node UUID's are resolved in ExpandNames and then stored in the
       OpCode. This allows to check for node renames if the OpCode is
       reloaded after a cluster restart. This check is currently only done
       for single node parameters.
     * Variable names are renamed to follow the following pattern:
       - Suffix is 'node' or 'nodes': Variable holds Node objects
       - Suffix is 'name' or 'names': Variable holds node names
       - Suffix is 'uuid' or 'uuids': Variable holds node UUID's
     * Tests are adapted.
