Reactive API clients should avoid using blocking calls. Current sender implementation is using sleep calls (utils.sleep4next) that shall be removed. Although the common sender implementation was already fixed to use scheduler instead of the sleep calls, the transactional sender implementation is still using it. Get rid of all the utils.sleep4next calls in TxSend class and use scheduler instead.
