* @brief RaiseFakeSuccessfulResponse raise event for the subscriber that

* resumption_data_processor().SubscribeOnResponse() need to be called to
* provide information that some data need to be resumed. So if pending
* request exists, SDL creates preliminary requests to HMI, subscribe the
* subscriber to this request but do not send it to HMI. It freezes this
* requests to precess the one by one when a response to the current request
* will be received When SDL receives a response from HMI it may satisfy some
* frozen requests. If it does SDL will create faked HMI response(based on the
* real one with corr_id replacement) and raise event. So that
* subscriber::on_event will be called with an appropriate response to the
* request that SDL was not sent to HMI.
* @param response message that will be raised with corr_id replacement
* @param corr_id correlation id that will be replaced in response to notify
