Reconnect after periodic Slack RTM disconnects?

We're seeing periodic disconnects in `SlackRTMAdapter` after a few hours. The maximum duration of a slack RTM session is 8 hours, so I figure it's that: https://api.slack.com/events/goodbye

I figure the right thing to do here is to reconnect, but I don't see logic for that. Is there a prescribed solution to this that I'm missing?
