The `TcpNetServerConnectionFactory.run()` must not block on the loop forever

[artembilan]

The current logic is like:

			while (true) {
				acceptConnectionAndExecute();
			}

This blocks a thread in the executor forever.
Fix it to while (isActive()) { to properly react to the stop() call.

Otherwise with an internal executor we wait on the:

					if (!executorService.awaitTermination(10, TimeUnit.SECONDS)) { // NOSONAR magic number
						logger.debug("Forcing executor shutdown");
						executorService.shutdownNow();

Which does not happen if we exit from the loop normally.
