        Set the relation data for each provider in the ``provided_data`` list.

        A provider must have a `name` attribute, which indicates which relation
        to set data on, and a `provide_data()` method, which returns a dict of
        data to set.

        The `provide_data()` method can optionally accept two parameters:

          * ``remote_service`` The name of the remote service that the data will
            be provided to.  The `provide_data()` method will be called once
            for each connected service (not unit).  This allows the method to
            tailor its data to the given service.
          * ``service_ready`` Whether or not the service definition had all of
            its requirements met, and thus the ``data_ready`` callbacks run.

        Note that the ``provided_data`` methods are now called **after** the
        ``data_ready`` callbacks are run.  This gives the ``data_ready`` callbacks
        a chance to generate any data necessary for the providing to the remote
        services.
