    :param waiter_name: The name of the waiter.  The name should match
        the name (including the casing) of the key name in the waiter
        model file (typically this is CamelCasing).

    :type waiter_model: botocore.waiter.WaiterModel
    :param waiter_model: The model for the waiter configuration.

    :type client: botocore.client.BaseClient
    :param client: The botocore client associated with the service.

    :rtype: botocore.waiter.Waiter
    :return: The waiter object.

        Note that the WaiterModel takes ownership of the waiter_config.
        It may or may not mutate the waiter_config.  If this is a concern,
        it is best to make a copy of the waiter config before passing it to
        the WaiterModel.

        :type waiter_config: dict
        :param waiter_config: The loaded waiter config
            from the <service>*.waiters.json file.  This can be
