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.

Cloud providers may need specific configurations to run properly (e.g.
authentication parameters, uri, etc.).
This patch adds the simplest implementation for passing configurations
to cloudproviders: a new apiserver -cloud_config flag to specify the
path to an arbitrary configuration file.
