    Use the driver to get limits

    @response_truncated was used to set the limit of returned entries. It
    asked the driver about the limit and set it to hints. With
    domain-specific configs, there are multiple driver instances and each of
    them carries domain-specific config.

    However, with domain-specific configs, the driver is not yet configured
    at that point, because sometimes the manager needs to perform additional
    actions in order to understand what domain it works with. Because of
    that, @response_truncated always got the limit from the default driver,
    not from the one actually used for the domain.

    Move the logic of setting the limit from the decorator to a private
    method, call it after determining the domain and driver.
