Making the global state reference a defined part of the node makes some parts of the block device processing easier and removes the need for other global values. The state is passed to PluginNodeBase.__init__() and expected to be passed into all nodes as they are created. NodeBase.__init__() is updated with the new paramater 'state'. The parameter is removed from the create() call as nodes can simply reference it at any point as "self.state". This is similar to 1cdc8b20373c5d582ea928cfd7334469ff36dbce, except it is based on I68840594a34af28d41d9522addcfd830bd203b97 which loads the node-list from pickled state for later cmd_* calls. Thus we only build the state *once*, at cmd_create() time as we build the node list. Change-Id: I468dbf5134947629f125504513703d6f2cdace59
