Remove SocketUtils usage

* Remove usage of non-stable `org.springframework.util.SocketUtils` * Replace it with `0` for those tests where it is possible to select OS port * Remove the mentioning of the `SocketUtils` from the `testing.adoc` * Use `TransportConstants.DEFAULT_STOMP_PORT` for `StompServerIntegrationTests`. We may disable this test in the future for CI if it is not going to be stable * Introduce `Supplier<String> connectUrl` variants for `ZeroMqMessageHandler` to let it defer connection evaluation until subscription to the socket `Mono` in the `ZeroMqMessageHandler`. * Move connection logic in the `ZeroMqMessageHandler` to `Lifecycle.start()` Related to spring-projects/spring-framework#28054 **Cherry-pick to `5.4.x`**
