cloudprovider: add instance id to NodeSpec

Browse Source 
Sometimes for external applications it is important to identify the
cloud instance of the nodes. Until this patch there was no contract
that the node name returned by List was also the unique identifier of
the cloud instance. This new API ensures that an external application
can reliably retrieve the relevant instance id of the nodes.
