Feature/Question Notify Webhook also when container is restarting

[alex-bronze-vision]

Hi,

As I can see from:

  if [ "$CONTAINER_NAME" = "null" ]
  then
    echo "$DATE Container name of (${CONTAINER_SHORT_ID}) is null, which implies container does not exist - don't restart" >&2
  elif [ "$CONTAINER_STATE" = "restarting" ]
  then
    echo "$DATE Container $CONTAINER_NAME (${CONTAINER_SHORT_ID}) found to be restarting - don't restart"
  else
    echo "$DATE Container $CONTAINER_NAME (${CONTAINER_SHORT_ID}) found to be unhealthy - Restarting container now with ${TIMEOUT}s timeout"
    if ! restart_container "$CONTAINER_ID" "$TIMEOUT"
    then
      echo "$DATE Restarting container $CONTAINER_SHORT_ID failed" >&2
      notify_webhook "Container ${CONTAINER_NAME:1} (${CONTAINER_SHORT_ID}) found to be unhealthy. Failed to restart the container!" &
    else
      notify_webhook "Container ${CONTAINER_NAME:1} (${CONTAINER_SHORT_ID}) found to be unhealthy. Successfully restarted the container!" &
    fi
    notify_post_restart_script "$CONTAINER_NAME" "$CONTAINER_SHORT_ID" "$CONTAINER_STATE" "$TIMEOUT" &

Webhooks are only triggered when containers are unhealthy and being restarted, but not when they are restarting by its own, maybe due to an internal error in the container.
I would be really nice to also notify that. I am opening this issue just to confirm that the modifycation that should be made is to add a notify_webhook when restarting:

  if [ "$CONTAINER_NAME" = "null" ]
  then
    echo "$DATE Container name of (${CONTAINER_SHORT_ID}) is null, which implies container does not exist - don't restart" >&2
  elif [ "$CONTAINER_STATE" = "restarting" ]
  then
    echo "$DATE Container $CONTAINER_NAME (${CONTAINER_SHORT_ID}) found to be restarting - don't restart"
    notify_webhook "Container ${CONTAINER_NAME:1} (${CONTAINER_SHORT_ID}) found to be restarting - don't restart"
  else
    echo "$DATE Container $CONTAINER_NAME (${CONTAINER_SHORT_ID}) found to be unhealthy - Restarting container now with ${TIMEOUT}s timeout"
    if ! restart_container "$CONTAINER_ID" "$TIMEOUT"
    then
      echo "$DATE Restarting container $CONTAINER_SHORT_ID failed" >&2
      notify_webhook "Container ${CONTAINER_NAME:1} (${CONTAINER_SHORT_ID}) found to be unhealthy. Failed to restart the container!" &
    else
      notify_webhook "Container ${CONTAINER_NAME:1} (${CONTAINER_SHORT_ID}) found to be unhealthy. Successfully restarted the container!" &
    fi
    notify_post_restart_script "$CONTAINER_NAME" "$CONTAINER_SHORT_ID" "$CONTAINER_STATE" "$TIMEOUT" &

If that is correct and the idea seems to be logical I can make a PR.
