Due to a Docker bug [1] we cannot use Docker to send SIGHUP to the container because it will mark it as stopped. This patch sends the signal directly to the process, bypassing Docker. 'changed_when: false' is also removed from the relevant task as it definitely changes the state. In the future we could do the refresh only if there really is a need for another one.
