When a container is left running after the daemon exits (e.g. the daemon is SIGKILL'd or crashes), it should stop any running containers when the daemon starts back up. What actually happens is the daemon only sends the container's configured stop signal and does not check if it has exited. If the container does not actually exit then it is left running. This fixes this unexpected behavior by calling the same function to shut down the container that the daemon shutdown process does. Signed-off-by: Brian Goff <cpuguy83@gmail.com>
