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.
