lookerbot to respond to botuser's mention

[lastcat]

I always use this handy product.When I want to detect abnormal values ​​and post dashboards to slack via the looker bot as alerts, I may want to have the lookerbot respond to botuser such as webhooks.
Of course I know about trigger functionality by datagroup. However, it is very nice to think about this proposal in order to reuse slackbot's mechanism of detecting anomalies and mentioning already.
