docstring: Retrieve the current state of the cluster and returns a ClusterSpec.
  
      Returns:
        A ClusterSpec representing the state of the cluster at the moment this
        function is called.
  
      Implementors of this function must take care in ensuring that the
      ClusterSpec returned is up-to-date at the time of calling this function.
      This usually means retrieving the information from the underlying cluster
      management system every time this function is invoked and reconstructing
      a cluster_spec, rather than attempting to cache anything.
