Gets the health of a Service Fabric cluster using health chunks.

        Gets the health of a Service Fabric cluster using health chunks.
        Includes the aggregated health state of the cluster, but none of the
        cluster entities.
        To expand the cluster health and get the health state of all or some of
        the entities, use the POST URI and specify the cluster health chunk
        query description.

        :param timeout: The server timeout for performing the operation in
         seconds. This timeout specifies the time duration that the client is
         willing to wait for the requested operation to complete. The default
         value for this parameter is 60 seconds.
        :type timeout: long
        :param dict custom_headers: headers that will be added to the request
        :param bool raw: returns the direct response alongside the
         deserialized response
        :param operation_config: :ref:`Operation configuration
         overrides<msrest:optionsforoperations>`.
